Wow, that is sweet! What a find! Here is a picture of a 1950 Bottecchia with Cambio Corsa drivetrain. It is quite similar. I would guess yours is from somewhere in the mid-50's. When did Campagnolo release their dropouts and fork ends? The fork crown on yours is unusual - notice the one on the 1950 bike is pretty much the same as the boom period bikes and my (presumably) 1967 frame. The seat stay attachment is quite similar though the lug is a bit different.
