little update to this,
a while ago i got the matching fork, had it painted then needed to cut the thread, which i have done today so then it was fit the fork/headset and stem.
i have also put some xt v brakes on it. not in keeping model year wise i know but as they were spare from my proflex (changed to maguras) and i didn't have a cable hanger for the headset i decided to pop them on as it gives more stopping power and it doesn't brake my canti hanger rule as the the frame and stem don't have hangers. i think it now has a really nice clean look.
i am interested to see how it rides now as the rc31 was 420 a-c and the correct fork is 400 a-c, i liked it with the rc31 but wanted the right fork in there.
also in regards to stevo's comment above, this frame i believe was cracked, where the e-stay meets the seat tube at the back on the small bridging bit of tubes, also around the seat clamp (but i think that was pure hamfistedness from the original owner) the cracks etc were sorted out when sinnett got if from the original owner (i collected and posted it to him) it all looks neat and tidy though and i have no qualms about giving it some welly!
