thanks for all of the help and advice. I'm slowly coming along. VCC do want membership, which is probably a worth while step, but I sort of messed up my finances and will have to wait a bit before going that way. I manged to piece together some nice bits as well, albeit not exactly period consistent.
I'm looking at a Campagnolo drive train; because i have the front which i got with the frame, and probably Mafac 'racer' brakes (again, because i have the levers that came with).
And then there was the unfortunate crankset I won on fleabay, only for the seller to send it to my US address instead of my UK one (and before I had even paid, noless!). So, hopefully in the next quarter I will get something done.
