Hello Norm,
I really like checking out older Cinellis. Heres what I can recall.
60s bikes: Dropouts with eyelets and fittings for fenders under the brake bridge and bottom bracket bridge. Drain hole on bottom of bottom bracket. Brass badge. 10mm hex head seatpost binder bolt. Headtube lugs do not have holes on top.
70s Bikes: Dropouts with eyelets, ect. (as above), but not always. Could have drain hole (as above) Aluminum badge. Allen head seatpost binder bolt. Headtube lugs with holes on top. Mylar SUPER CORSA seattube decal.
Sometimes components are changed out over a period of time.
I'm sure I missed something.

The current owner bought it used in the early to mid 70's and described it as an early 70's bike. But in conversation he said that it originally had a Record steel rear derailleur and Universal 68 brakes. I suspect that this would indicate a 60's bike but I don't know what frame details to look for to verify this. Also I don't think the steel derailleur and Universal 68's existed at the same point in time. What should I look for on the frame to determine the vintage? He also said it was in rough shape but I have to look...not everybody has the same tolerance for patina.
