The frame looks to be from the 70’s, but Saronnis weren’t produced until the early 80’s.

Saronnis had panto’d seat stay caps and fork crown, neither of which are on this frame.

I believe Saronnis had two cable guides on the top tube, there isn’t any here.

The decals don’t look like any Saronni I’ve seen, and usually Giuseppe’s handsome face is on the head tube.

So IMO someone has put Saronni decals on what looks to be a nice 531 frame.
