My bike has the white circular CARNIELLE sticker below the TT. Same headbadge. Same black&white checkered squares on the top tube. Universal brakes, maybe not the same model (no red paint fill-in on mine). Mine has script "Giro'd Italia" between b&w squares.
The rumor I heard was that the top 2 frames were identical. Maybe fork, too.
Mine is 58.5cm square (ctc) with a 16cm HT. Record RD & Campy shifters, Nervar Star crank.
It was purchased new in western Canada in Spring of '72or'73, original owner wasn't sure.
edit: Came with tubular wheels, which owner switched to clincher.
Wondering how yours might differ? Can't judge your frame size from the above pic.
