LC, I'm not sure where you read that the SUPER was an entry level frame. The info I've been able to find says that the Super was the top of the line frame, made from SL tubing, until about 1983, when the Master came into being. I think there were even Super Mexico models, in ref to Eddy Merckx's 1972 World Record in Mexico 1972. In other words, I think the Super is as valuable as any Master, though Masters seem to be more in demand because of the Gilco tubing. Anyway, that's what I've read, as is the following, 'stolen' from the interwebs!! ========================== Colnago Super Frame Dating (12.18.2011) ========================== 1968 -- "Super" decal on chain stay 1968 -- Fork crown (sand cast) with two holes in the points at each side 1968 -- Fork tangs wide, no cutouts 1968 -- Club cutouts in all three lugs 1968 -- Bottom bracket shell with drilled holes (eight in circle plus one in center) ---- 1970 -- Fork crown (investment cast) semi-sloping, flat front and back with two holes in the points at each side 1970 -- "Playing card" club decal graphics (inspired by 1970 Milano-San Remo victory) ---- 1971 -- Fork crown with clubs in top and two holes in each side 1971 -- Fork tangs narrow, no cutouts (or rarely no tangs) 1971 -- Club cutouts in all three lugs but club in lower head lug is now larger 1971 -- Hole in lower point of seat lug (last year) 1971 -- Bottom bracket shell with club cutout ---- 1972 -- Black Club/COLNAGO decal on head tube/seat tube (two seat tube Worlds bands) and COLNAGO on down tube 1972 -- Fork tangs with two holes (or very rarely three holes tangs or no tangs) 1972 -- Derailleur cable guide braze-ons top of bottom bracket shell 1972 -- Water bottle braze-ons on downtube ---- 1973 -- Wreath seat tube decal with Worlds band at top and bottom 1973 -- Fork crown with clubs on top but no holes in each side 1973 -- Fork tangs with club cutouts (or rarely two hole tangs or no tangs) 1973 -- Club cutout in lower head lug only 1973 -- Introduction of the Super Pantografata ---- 1974 -- Shifter braze-ons on down tube (option before this) ---- 1975 -- Mexico model introduced 1975 -- Diagonal Worlds band added behind black Club/COLNAGO head tube decal 1975 -- Diagonal Worlds band with yellow Club/COLNAGO head tube decal used for one year 1975 -- Vertical COLNAGO seat tube decal with single diagonal Worlds band at top ---- 1976 -- Fork crown with COLNAGO added to clubs on top 1976 -- Short Campagnolo or COLNAGO dropouts ---- 1977 -- Fork crown with shallow triangles cut into back (no recessed brake bolt) 1977 -- Top tube brake cable guide braze-ons (an option before this) ---- 1978 -- Fork crown for recessed brake bolt with shallow triangles cut into back 1978 -- Brake bridge for recessed brake bolt ---- 1980 -- Fluted seat stay caps engraved COLNAGO and straight seat stays (no longer biconical shape) 1980 -- Brake bridge with cast square boss for recessed brake bolt ---- 1981 -- Chain stay bridge is small spool shape (no longer tube shape) ---- 1982 -- Chain stays stamped COLNAGO on sides 1982 -- Derailleur cable routing on underside of bottom bracket ---- 1983 -- Aerodynamic fork crown NOTE: Year dates are approximate; changes might have occurred the end of one year or the beginning of the next for example. Paint schemes, panels, decals and chrome varied according to how importers spec'd their frames, so this all varied considerably and there are anomalies. Dates and details based on the Classic Rendezvous archives, the Wool Jersey Gallery, and Colnago and Bikcology catalogs. Serial numbering only started for Colnago on USA-bound bikes when the CPSC started requiring tracking, etc. West Coast Cycles was importing Colnago at the time and the serial numbers started for their product. There is still no way to determine manufacturing date by the numbers, except that they are 1979 or later....
