The Olimpiade has forged dropouts and would have a Campagnolo crank. The Mezza Corsa had no chrome. So yours looks like a Gran Premio. Interesting that Randy's has forged dropouts.
Both of my Gran Premio's have forged dropouts, a
1962 and a
1974 (no chrome). I also think that this example is most likely a third tier model, but still desirable in my view. But then I like weird stuff.
