Your pic of the full bike is exactly as my 1974 as-found, right down to the blue band on the down tube. The bike appears to be a '74 Molteni replica (as in: replica of the colors of Eddy's team bikes, branded Merckxs). Pic seems to show the long Campagnolo 1010a rear dropouts, short fluted seatstay caps and the rear derailleur cable stop about 3" from the dropout. If the fork crown has clovers but no "Colnago" engraving and there are two round holes in the fork stiffening tangs, I'd lay money on '74. '75 they changed the decal set and began to use fork tangs with a clover cut out, and the fluted seatstay caps were longer.

That said, $1200 is a bit much as the couple of detail shots clearly state: for that money, you don't want any dents - although paint chips come with the territory - and the components should be in fairly good shape and consistent with the period. In one pic there is a pedal displayed that is certainly not period correct!

Good luck, and share more if you get this rough diamond.
