The Internationals of that vintage came with a 14-24 5 speed freewheel, though the Professional models came with a 6 speed. I think any previous owner would have a hard time resisting the upgrade to a 6 speed, which would have prompted the frame mod.

A bit of cold-working is fine, but back-and-forth?
I've cold-set a number of early 70s Raleighs back to original spacing without issue. The 72 Supercourse (my commuting bike) went from 120 to 130 then back to 120. Anything more than 10mm though would probably be too much though.
