Yes, indeed...build ride and enjoy is definitely where it's at. However...after a bit more trawling last night I think we now have an answer....I think what I have is an Excelsior Condex C1 from 1956. No pictures of a real one anywhere that I've thought of looking but there are a number of pieces of publicity blurb out there that refer to this being in the model range in 1956. Forks, head stock, frame, rear plunger suspension, tool box and everything look identical to what I have in my pile of bits...even the colour is correct. The engine appears to be a 150cc Villiers, not one of Excelsior's own.
Attached is a shot of one of the documents I found...the model I think I have is the bike on the top left. As already pointed out though the engine I have is a 197cc. Will have to decide whether to go with what I have or go phaff around trying to locate the correct engine.
There was an earlier model Condex, the D12, which had a smaller engine (122cc I think) a hard rear end and I think girder front forks, painted black. There appear to be a few D12 models in circulation still, but few similarities to what I have if any.
So, if anyone has a Condex C1 from 1956, can I have some pictures please?
Thanks for all supportive and informative replies.
