I agree the headlug points are odd, but I was just reminded by another member to never say never. It's too bad you could get the frame "cheap" but I don't think the remaider of the restoration would be worth the expence.
To be honest, Cambio Corsa frames are not all that tremendously rare (Paris Roubaix frames are more rare). With a little patience, they can be obtained pretty economically - but then you have to do the build, or have your dogbones already in hand (as Ben Franklin famously wrote ... or was that birds?)
