The Douglas factory stamped some parts, like this tappet from a 1936 Aero, with the DK symbol shown in the picture. DK stood for Douglas Kingswood. Their stamping ‘policy’ is not entirely clear, as the other three tappets are plain – but next time you’re rooting through a box of bits at an autojumble and come across the DK symbol, at least you cannot say you Don’t Know – it’s definitely Douglas! Did this stamping practice continue post-war? If you know the answer, please add a comment below.
These photos were sent in by the great niece of the rider, who asks if anyone can tell her anything about the machines or location. The earlier machine, LG4760, is registered to Cheshire County Council while the later machine RN9017, which looks like an Endeavour, was registered in Preston. This appears to have been taken in a holiday camp and the rider’s light trousers and his wife’s white shoes suggest that it was ‘posed’! Charlie Sim was a talented musician who played trombone with the Billy Cotton Big Band in the early ’50s. If the pictures ring any bells, or you have the machines in your shed, we’d love to hear from you.
