Thanks Eric F - - those are very interesting shots. One 'expert' assured me that the Colnago frames were 'never' welded only lugged - so hope he see these photos!!!! Also these two frames are'nt ovalled horizintally as was suggested earlier. They look just about circular as does mine. However, I am reconciled that the one i've found isn't a Colnago, which is a shame!
One thing I did see is that you have (had?) a 2001 Conago in your 'owned' list - could I ask what the frame number is for that please? No-one has yet come up with nay info on what sort of numbering system the company might have used.
Thanks again, Happy Riding,
Richard
