This photo: http://www.raydobbins.com/misc/Colnago_Catalog/1024/07.jpg shows the typical indentation in the chainstay for tire clearance and also a dark line down the center of the tube all the way back to the dropout which I am certain is not a crimping because the same dark line appears down the center of each seatstay which I am absolutely certain are not crimped.

To be brutally honest, I never really paid much attention to crimped tubed Colnagos because I thought they were a little silly from an engineering standpoint, of course only my opinion.

1981 based solely on the chainstays with the stamped "COLNAGO" in the side.
