I don't think it looks original...

As regards dating of blue frame. It appears clearly later than 1965 to my eye. IIRC Carnielli changed their lugs for the road models ~1968. Caveat - am not one of the forum's Carnielli experts so if am incorrect am happy to defer to those with greater knowledge.

I tend to agree on your post 65 thought. This one looks identical to my white frame, which I think is late 60's, perhaps 70 or 71. Lugs and all, its the same. The only stylistic difference I see is the use of pinstriping around the lugs. It's red on my frame, and white on the blue one you posted a picture of.
One date hint could come from the bottom bracket. It's a late stepped cup Nuovo Record, but I've not been able to figure out yet when Campagnolo changed the design. Of course, dating the frame based on this would require a leap of faith that the bottom bracket is original.
