Can you help to identify these frames, bikes or parts?

The person i bought it from has put a colnago sticker on the frame, did colnago make frames with 631, Didn't they use columbus? Also is there anyway to determine if it is a colnago? I know it has long shen lugs but i guess loads of frames have them regardless of tubing... did you ride it in sheffield when it was on ebay?

I rode it in Hull, maybe he moved?
I can not help with anymore info, however the bike felt light and stiff and very responsive!
At the time I had a Harry hall believe to be Columbus tubing and it felt very similar!
Just ride the hell out of it and enjoy it!
