Hi there, I have recently become the lucky new owner of a 1921 V twin sunbeam with a J A P 980cc motor. There are a few parts missing including the rear drum brake actuating arm and adjuster. It is an unusual type: the arm fits onto a smooth taper with a key way. Does anyone know if this type of brake actuator was fitted to any other sunbeams, and if so which model(s)? I am trying to get hold of one (and the adjuster), so if any one has a spare they'd sell, I'd be delighted to hear as it is a tricky thing to make. Hopefully they were fitted to other sunbeams , but so far everyone I have asked is not aware such a type was fitted to other models. Many thanks, Jamie
I've just had a look at the parts lists on the Sunbeamland website.It looks like this arm and key were fitted to 1914/1921 bikes .theres no later reference for the part number that I can find
