Wore out three sets of tires already!
I had gotten this as a parts frame set for the fork to use on another frame, and didn't use the frame due to overall paint/decal condition, as well as some rust damage on the driveside seat stay. Stay was not in a non-functional state, but it is brazed with brass at the damaged area and I did not want to sell the frame to someone with myself already knowing its condition; but it is still fine for me. New paint could hide the issue, but I would still know the truth. Original paint before fading looks "Saronni red" in color being of a darker hue than their standard red paint.
The main issue is determining if it is a "Super" or "Mexico" model. I never really looked at its features since the fork was all that interested me at the time. The frame feels quite lightweight (for its size) but I have not hung it on the scale. 27.2mm seat post fit. It has features of early 80s to mid 80s. Decals are more mid 80s, fluted stay caps are more early 80s; Prugnat lugs. Later and smaller BB cut-out presumably allowing for bottom mounted cable guide braze-ons. Down tube only bottle mounts. It has a "COLNAGO SUPER" decal on the left chain stay, but although I believe it to be original, I do not think it is correct to the actual model. "Super" models of this time had chain stay indents both on the wheel sides and chainring side; the "Mexico" models did not. The fact that it has no "COLNAGO" stamped into the chain stay would indicate an early 80s (pre 82-83?) model frame. Brake mounting is recessed, brake bridge is the same "GPM" model as used on late 70s to early 80s models.
Any ideas? Did Colnago put the wrong decals on it? Pretty sure that "Mexicos" had a different seat tube design with the record date on it (at least pre "Nuovo" models). I don't know if the weight will provide an answer as to it being a Columbus "SL" (Super) or "Record" (Mexico) tubed frame.
I do not know when Colnago changed the BB cut-out, but I know the early style still was in use through circa 1981. Latter 80s BBs had "COLNAGO" stamped above or below the cut-out. I don't know how long this style BB design was used. I had an '86 "Mexico", but cannot remember the BB design; I'll see if I can dig out an old photo or ask my friend to whom I sold it to for some input as to its design.
My thought was to build it up into a beater Colnago. There is an old Campy decal on it, but I would use non-Campy Italian parts.
Photos to follow shortly when I grab it from my store room.
