I have just read the link write-up on these frames (Thank you fabiofarelli ). I now know that this is a "Special Professional" with Columbus SL tubing; outstanding! I will make sure it gets done right with a professional paint job (probably keep it the same color) and some period Italian parts. I wonder if there is a way to determine the year. There is that odd backwards "S" that is on the BB shell and steerer tube. Could it be a year indicator or the mark of the actual builder? I now need to see what the actual decals need to be. The fork crown must be fairly early as it is flat, there are bosses for a bottle cage, and braze-on shifter mount bosses. I figure more 70s than 80s with that crown design. Does anyone have a known year example?
