You're right about the derailluers on the CCM. They are Simplex, not Huret (faulty memory on my part. I stripped them to do the fixed conversion and never looked closely at what they where). Rear one says "Prestige" on the back. Crank arms are stamped "Forged 171 47-11". Also found "HB" stamped on the BB shell, but no serial numbers. Frame has the remains of a Reynolds sticker. 531 main tubes I think, but am not sure.

Frankly the quality of the frame construction on the CCM is much lower than that of the Dolomiti. Bad fit to the lugs, ugly welds, crudely capped straight seatstays as opposed to tapered stays on the Dolomiti and stamped dropouts and pump pegs.

The CCM was a $20 Craig's list find that I converted for a friend who later decided that fixed is not for them, and is of a known, or at least knowable, pedigree. To me it is not nearly as interesting as the Dolomiti which no one has heard of.

BTW - Thanks for your time and input.
