Last New 4.5 Litre – OSCA 4500G

Leave a Reply

Ten years after selling the company bearing their name to Adolfo Orsi in 1937, and remaining for those ten years as employees of the company, the Maserati brothers founded Officine Specializzate Costruzioni Automobili – Fratelli Maserati SpA better known as O.S.C.A in 1947.

Towards the beginning of the 1951 Grand Prix season Prince Bira had one of his three year old Maserati 4CLT/48’s fitted with a new 4.5 litre OSCA 60º V12 motor that produced 330hp to replace the regular 1.5 litre 4 cylinder supercharged motor.

The Prince recorded a debut win with the new motor in the Richmond Trophy at Goodwood and raced with it on at least four further occasions scoring a best 4th in the 1951 Bordeaux Grand Prix concluding his season with a retirement from the 1951 World Drivers Championship Spanish Grand Prix after completing just 1 lap with engine failure.

A little over a month before the Spanish Grand Prix O.S.C.A turned out with their own Formula One challenger, today’s featured 4500G powered by the same type of alloy block V12 as they had supplied to Bira.

Franco Rol qualified 18th of the 21 starters for the 1951 Italian Grand Prix and completed all but 13 laps of the full distance to be the last classified finisher, in a career high, 9th place.

In the absence of sufficient commitment from manufacturers to continue with the 1.5 litre / 91.5 cui / supercharged / 4.5 / 274.5 cui litre normally aspirated Formula One powered cars, the 1952 and ’53 World Drivers Championships were decided by running the series for 2 litre / 122 cui Formula Two cars.

Consequently the last all new type to appear in the 1951 Formula One championship season and the only car built specifically to compete in Formula One races by the Maserati brothers remains the OSCA 4500G seen in these photographs at last years Silverstone Classic being driven by Stephan Rettenmaier.

Pole Sitter & Sister – Shadow Cosworth DN5 #DN5/1A #DN5/2A

1 Reply

Things were looking up for reigning Can Am Champions Don Nichols Shadow team in 1975, the Can Am series folded, but the team kept a strong US presence with a Dodge powered DN6 Formula 5000 team which used a similar Tony Southgate designed chassis to today’s featured DN5 design.

Following the dominant trend in F1 design the DN5 was built around a slimmer lower monocoque, than the previous years DN3, but with a longer and wider wheel base and track than many.

Shadow DN5, Silverstone Classic,

Jean Pierre Jarier put the DN5 #DN5/1A, seen here in the first third and sixth photographs at Silverstone Classic 2013, on pole on the cars debut in Argentina, but the car never started having stripped the crown wheel and pinion in the gearbox on the warm up lap.

Jumper was on pole again at the 1975 Brazilian Grand Prix, but retired seven laps short of the finish after the fuel metering unit failed.

Shadow DN5, Donington Park Museum,

The non championship Race of Champions at Brands Hatch saw the DN5’s run with a new TV test card like colour scheme and Tom qualified the sister #DN5/2A, seen in the close ups at Donington Park Museum, on pole and then ran away with the race while Jean Pierre finished 4 laps down from 3rd on the grid classified 8th with a fuel pump issue.

Further highlights of the season came in Spain where JPJ finished a season high 4th from 10th on the grid and at Monaco where still driving the two original chassis Tom and JPJ qualified 2nd and 3rd respectively, but both retired with accident damage which would be the final appearance of JPJ’s #DN5 1A.

At the British Grand Prix run at Silverstone Tom won his only career championship pole but retired after an opening lap accident, by now having scored two 6th place finishes in Belgium and Holland.

Shadow DN5, Silverstone Classic,

In Germany Tom still driving #DN5/2A converted 16th on the grid to a fourth place finish.

Meanwhile keen to find another engine supplier the similar Shadow DN7 with a V12 Matra engine, which I looked at a couple of weeks ago, had been built up for JPJ to drive in Austria and Italy.

Shadow DN5, Donington Park Museum,

While the Matra proved not to be quite the fillip to the team’s fortunes that were anticipated Tom drove #DN5/2A to the teams season high 3rd place finish in Austria from 15th on the grid.

At the non championship Swiss Grand Prix run at Dijon in France JPJ was once again on pole with the Cosworth powered #DN5/4A, Jumper looked like he was going to break his F1 duck, until the 34th lap from 60 when the transmission broke and he retired from the lead.

Shadow DN5, Donington Park Museum,

At the Italian Grand Prix Tom once again drove through the field coming home 6th from 14th on the grid.

#DN5/2A’s final appearance came at the 1975 US Grand Prix where Tom qualified 7th but finished unclassified 7 laps down.

Shadow DN5, Silverstone Classic,

Having failed to convince Matra of their suitability as a partner for the 1976 season Shadow also lost their sponsor UOP meaning Tony Southgates new Shadow DN8 was put on hold while the team continued running the DN5’s in B spec, which I shall look at next year, that was introduced to meet new regulations from the Spanish Grand Prix.

Shadows and Reflections – Silver Jubilee Silverstone Classic

Leave a Reply

Today’s post features some of the more off the wall stories behind last months Silver Jubilee Silverstone Classic.

Bristol MW6G, Silverstone Classic

Greeting VIP’s in the VIP car park on the Friday was this 1962 Bristol MW6G (Medium Weight originally fitted 112hp Gardiner 8.4 litre 6HLW 6 cylinder engine). Royal Blue operated out of Bournemouth from 1880 to 1986, this coach is one of at least two owned by the White Brothers in Gaydon.

Jaguar XK150, Silverstone Auctions, Silverstone Classic,

On the Thursday I attended the auction, for the first time since the 1980’s, and among the lots was this 1958 non matching numbers Jaguar XK150 in need of a little TLC which sold for a tad over £20,000 pounds, or the price of a couple of brand new Dacia’s.

Cooper Monaco, Silverstone Auctions, Silverstone Classic,

Waiting ready to race was the Cooper Monaco chassis CM/2/59, its early history is unknown to me, but more recent owners have included Frank Sytner and Bristolian Ted Williams. The Cooper was bought for just short of £220,000 by Justin Maeers who claims he only popped in to the auction for the free beer. After Charles Gillet blew the engine in his Willment Climax the following day Justin came to an agreement to enter his newly acquired Cooper in it’s place for the Stirling Moss Trophy race. Starting from the back of the grid Justin unfortunately damaged the gearbox after just two laps.

Porsche 911 RSR, Cooke, Dowd, Silverstone Classic

When the heavens seriously started to open during qualifying on Friday many of us with camera’s caught in the rain went for some reflection shots, above the Martini liveried 1974 Porsche 911 RSR of Jeremy Cooke and Mike Dowd which qualified 32nd for the FIA Masters Historic Sports Car race was probably my best effort.

Shadow DN8, Jason Wright, Silverstone Classic,

It was a pleasant surprise to see not one but two recently restored 1977 Shadow DN8’s taking part in the FIA Masters Formula One race, above Jason Wright which has a two race history at the end of 1977 when Jean Pierre Jarier replaced Ricardo Patrese at the Canadian Grand Prix and finished 9th and Ricardo finished a non runing 10th at the US GP the following week.

Bugatti T35, Duncan Pittaway, Bentley Blower, J Ernst, Silverstone Classic,

Taking time off from running his monstrous show stealing FIAT S76 was Duncan Pittaway who is seen wheeling his #13 Bugatti T35 passed the #47 Bentley Blower driven by J Ernst on his way to a 7th place finish in the Kidston Trophy for pre war cars, from 8th on the grid.

Arrows Megatron A10B, Mike Wilds, Silverstone Classic,

Demonstrating the Turbo Megatron (BMW) powered Arrows A10B was the severely underrated Mike Wilds who just made it to Formula One with the struggling Ensign team then to BRM when BRM was collapsing and since then he has been racing all manor of vehicles including a Shadow DN3, Can Am BRM, Production Saloon 16 Valve Mercedes Benz 190 and numerous Sports and Group C cars at Le Mans.

BMW 3.0 CSL, Peter Mullen, Ford Cologne Capri, Rick Wood, Silverstone Classic

Alpina, celebrating it’s 50th anniversary this year, took a famous RAC Tourist Trophy at Silverstone in 1973 when Derek Bell and Austrian Harald Ertl driving an Alpina BMW 3.0 CSL claimed a 3 lap vicotry over solo driver Jochen Mass in a works Ford RS2600 Cologne Capri, on this occasion Ric Wood in the 1974 24 valve RS3100 Capri got the better of Peter Mullen in the Alpina BMW on their way to finishing 20th and 24th in the Super Touring Car Trophy.

Rover BRM, Silverstone Classic

Completely unannounced the Rover BRM which Graham Hill and Jackie Stewart drove to a 10th place finish in 1965 came whistling by on a demonstration lap, I have no idea who the driver was.

Bristol MW6G, White, Silverstone Classic

Finally the White brothers 1966 Hants & Dorset Bristol MV6G was on VIP duty all day on Saturday.

Thanks for joining me on this “Shadows And Reflections” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow when I’ll be looking at another 1975 Formula One contender. Don’t forget to come back now !

Leave a Reply

Welcome to another Ferrari Friday edition of “Gettin’ a l’il psycho on tyres” this week brought to you from last month’s Silver Jubilee Silverstone Classic.

Ferrari 365 GTB/4, Silverstone Classic,

There were plenty of disguised Ferrari’s present such as this 1973 Ferrari 365 GTB/4 chassis #16643 which left the factory as a 2+2 Berlinetta and was converted into a Spyder in 1988, this car is reported to have recently been upgraded with a Traffic Master tracker, Autowatch immobiliser and iPod stereo connection.

Ferrari 365 GTB/4, Silverstone Classic,

Still carrying it’s original Scaglietti 2+2 Berlinetta body above is the 1970 365 GTB/4 chassis #13775 that was owned by “20th Century Boy” Marc Bolan who famously never learned to drive fearing premature death only to be tragically killed when a passenger in a Purple Mini 1275GT driven by his partner in 1977.

Ferrari 275 GTS, Silverstone Classic

Another Ferrari with a famous owner is the 1965 Ferrari 275 GTS chassis #07395 seen above which once belonged to 1980 Australian Formula One world champion Alan Jones.

Ferrari 250 GT SWB, Halusa/Halusa, Silverstone Classic

Also no longer carrying the body it left the factory with is the famous 250 GT SWB chassis #2819 which Count Volponi had hastily converted to a GTO spec with Breadvan body by Giotto Bizzarini and other ex Ferrari personnel. The car was shared by L & N Halusa and is seen during qualifying for the Sunday TT race in which it finished 17th from 16th on the grid.

Ferrari 250 GTE, Silverstone Classic

I have not yet been able to discern a chassis number for the 1961 Ferrari 250 GTE above, if you know it don’t hesitate to chime in below.

Ferrari 250 GTE, Silverstone Classic

The replicated TR body above also sits on a V12 250 GTE which I believe is the 1963 chassis #4873.

Ferrari 246S, Gregor Fiskin, Silverstone Classic

Finally congratulations to Gregor Fisken who is seen above dancing the, GALPOT site banner car, 246S #0784 through Chapel on his way to a win in the Stirling Moss Trophy.

The Road Racer Dream – Chapman Mercury III

Leave a Reply

Sheffield auto electrician Phil Chapman dreamed of owning a car he could drive on the road and race at weekends. Short of the necessary brass to buy a vehicle to fit his needs, but blessed with the necessary curiosity, common sense and initiative, he taught himself how to build his first special based on a 1930’s Triumph chassis with Mercury V8 power in a corrugated iron shed in the late 1940’s.

Chapman Mercury III, Oliver Tomlin, Chateau Impney Hill Climb

In 1952 he put the engine into a space frame of his own design known as the Chapman Mercury II and four years later dismantled it to build a second space frame, drawn out in the time honoured way with chalk on his workshop floor, the Chapman Mercury III seen in these photographs.

Chapman Mercury III, Oliver Tomlin, Chateau Impney Hill Climb

After making the molds for the glass fibre body Phil campaigned the car successfully into the early 1960’s including at the original Chateau Impney Hill Climb where the car is seen here driven by Phil’s grand son Oliver Tomlin.

Chapman Mercury III, Oliver Tomlin, Chateau Impney Hill Climb

Phil sold CM III to make way for the Chapman Mercury IV which featured an all wheel drive system of his own devising, this car proved problematic but was sold on when Phil temporarily gave up motorsport in favour of gliding.

Chapman Mercury III, Oliver Tomlin, Chateau Impney Hill Climb

In the 1970’s Phil took the opportunity to buy the Chapman Mercury III back as a retirement project and after restoring the car he went on to compete in her again with his daughter Sandra, now Tomlin, who went on to claim the ladies records at Wiscombe Park, Gurston Down, Prescott, Shelsley Walsh, Loton Park and Harewood hill climbs in more powerful open wheel vehicles.

Aqueous Friday – Silver Jubilee Silverstone Classic

Leave a Reply

Weather predictions have been pretty unreliable in this neck of the woods this year so when I was told that an aqueous qualifying day was predicted for the Silver Jubilee edition of the Silverstone Classic I paid little attention beyond checking my wellies and rain coat were packed.

Alexis HF1, Duncan Rabagliati, Silverstone Classic

Qualification started bearably moist as Duncan Rabagliati, driving his #7 Alexis Mk 1 and his fellow Formula Junior competitors hit the track.

Lister Chevrolet Knobbly, Roberto Giordanelli, Silverstone Classic,

As practice for the Stirling Moss Trophy came to an end I headed out to Brooklands where Roberto Giordanelli is seen kicking up a little spray aboard his Chevrolet powered Knobbly Lister.

Frazer Nash Supersports, Hall / Grant Peterkin, Silverstone Classic

As the Pre War Sports cars came out qualify for the Kidston Trophy the heavens opened up and I was caught in the wrong place in the wrong attire as Andrew Hall and Michael Grant Peterkin took turns in coming to terms with their severely under steering chain drive Frazer Nash Supersports on their way to fifth on the grid.

Jaguar E-Type, James Cottingham, Silverstone Classic,

Above James Cottingham drifts his #73 E-Type Jaguar through Club corner above on his way to second on the grid for the Tourist Trophy race.

Williams FW07C, Christophe d'Ansembourg, Silverstone Classic

Christophe d’Ansembourg entered Abbey curve backwards and is seen passing the apex at 90º to the track before recovering from the mother of all tank slappers without exceeding the track limits to qualify his Williams FW7C for the FIA Masters Historic Formula One Race 21st from 38 runners.

Audi 80 Quattro, Frank Wrathall, Silverstone Classic

With all wheel drive one might have expected Frank Wrathall to be a contender for pole in his Super Tourisieme Audi 80 Quattro however since the whole Super Touring Car qualifying session was run behind the safety car he was only awarded 13th place on the grid based on previous form.

Kurtis KK500C, Geriant Owen, Silverstone Classic

Conditions such as this would never be tolerated at Indianapolis but Geriant Owen put on a fine display of driving skill and qualified his 1954 Kurtis KK500C roadster a fine 12th for the Maserati Centenary Trophy race.

Nissan R90CK, Bob Berridge, Silverstone Classic,

Bob Berridge’s Japanese Group C spec Nissan R91CK will have been no stranger to monsoon conditions and so it was perhaps no surprise he qualified on pole for the Group C race, following in the US GTP spec #5 Spice SE90P is Steve Tandy who qualified 9th on the sadly depleted Group C grid.

Bizzarrini 5300 GT, Tim Harvey, Silverstone Classic

Roger Wills stepped down from driving his collection of cars this weekend and let Tim Harvey do the hard work, above Tim gets to grips with Rogers Bizzarini 5300GT which was awarded 7th on the grid for International Trophy for Classic GT Cars as once again the whole session had to be run behind the pace car.

Porsche 911 RSR, Mark Bates, Silverstone Classic

Mark Bates took full advantage of the tricky conditions to drift his Porsche 911 RSR to an unexpectedly high 4th on the grid amongst a gaggle of more powerful Lola T70’s and faster 2 litre / 122 cui Lola and Chevron sports racing cars on the FIA Masters Historic Sports Car grid.

Fortunately as we will see next week the rain eased off over night to make for an interesting day’s racing on Super Saturday.

Dealers Special – Peugeot 302DS Darl’Mat Cabriolet #705538

Leave a Reply

Emile Darl’mat was a Peugeot dealer with a body shop who started offering special bodied Peugeot 302 and 402 based coupes and cabriolets in the 1930’s and went so far as to enter a team of cars for the Le Mans 24 Hour race in 1937 and 1938.

Peugeot 302DS Darl'Mat Cabriolet, San Marino Motor Classic

Today’s featured car is based on the Peugeot 302 but fitted with an 1991 cc / 121 cui four cylinder engine from the larger 402 which could be tuned by Darl’Mat to give up to 15hp more power than the standard 55hp. The deco body work was designed by Georges Paulin and built by Carrosserie Pourtout.

Peugeot 302DS Darl'Mat Cabriolet, San Marino Motor Classic

Chassis #705538 resided for many years with the Schlumpf Collection in Alsace and was brought up to it’s present condition by the Mullin Automotive Museum after being purchased by Peter W. Mullin.

My thanks to Goeffrey Horton for sharing these photographs taken at the San Marino Motor Classic last year.
