KEW, do you still need any original parts for your Pro Am? I've recently swapped out some of the original parts on mine to make it more suitable for commuting use.
I've got the front and rear derailleurs, handle bars with levers and brakes. If you need them to complete your project you're welcome to them for no charge.
I live in Canada now, but I'm coming back to the UK in November, so I could bring them in my bags and ship them when I get there.
Also got the gear levers
I do have the original wheels, including 6 speed gearset as well, but don't think they will fit in my bags. If you want them I can ship them from Canada, but you'd have to pay the shipping! They seem ok, I can email you photos if you like.
