Six months before production of the Plymouth PA came to an end production of the PB commenced on February 4th 1932.

The PB would be the last 4 cylinder model using the same 196 cui / 3.2 litre 4 cylinder motor inherited from both the PA and earlier U series Plymouths, though now with oil filters fitted as standard equipment.

The 109″ chassis was the same wheel base as the PA and U series to but with X pattern cross bars for additional chassis rigidity.

The hydraulic brakes were also upgraded to a centrifuse type featuring steel drums with fused cast iron friction surfaces.

It is believed that 2,163 PB Convertible Coupés were built like the example seen here in a California car park, though they were only available new from the factory painted; Black with either Black or Casino Red mouldings, Limousine Blue No. 4, Uhlan Gray, Merrimac Beige, or Biscay Sand, bodies, the 4 cylinder PB’s would be replaced by 6 cylinder PC’s and PD’s in 1933.

My thanks to Geoffrey Horton for sharing his photographs.
