Hi, we know nothing much about this bike and I am not too sure about uploading photo`s to this forum is it easy??, my father only stored it for a racer by the name of Catlin, he did not race it though it was one he had collected, most of the work done on the bike looks to be well engineered but the bike is very neglected and rusty, it has an expansion pipe that looks to go up under where the seat would be if it had one and rear sets are bolted to the frame in front of the rear plunger units. I have photo`s (not good ones) but will post if ever I can fathom out this forum, Many thanks Trev.
