Description
Sunbeam 1938 “High Camshaft” model B 24 347 cc OHV frame# 1053 engine# 735
In the mid-thirties Sunbeam parent company ICI ( Imperial Chemical Industries) decided to dispose of the hardly profitable cycle and motorcycle side.
AMC bought the business in 1937: their main interests being the bicycle dealer network and the well-establish famous “Sunbeam” name. Production moved from Wolverhampton to Plumstead.
That’s to say, there was so much stock that it was enough to sustain production in London for more than a year.
At the end of 1938 a new line of OHV machines was presented, ranging from the 250 cc B23 to the 600 cc B28.
The enginewas of the high camshaft type with the cylinder barrel sunk deep into the large crankcase.
It had a large timing case with “Sunbeam” script which contained a long chain that drove the magdyno and was tensioned by a Weller tensioner.
The cycle parts were also improved, notably the 8 inch front rake was a good stopper.
The “B” series was also catalogued for 1940, but early in that year AMC needed its full capacity to produce the Matchless G3 army models; the Sunbeam tools and production lines were dismantled, never to be used again…
This machine has not been restored and is equipped with a four speed foot change Burman gearbox which was standard with Sunbeams from 1936 on.
