I’ve 60/70’s bikes a Brit 531 and a Gios both come in c-c at 58/56 I def remember frames mid 80’s to ‘square’ i.e 58/58 especially a lot though not all Italian frames .weghtwise there was a lot of higher up weight ,alloy posts were v thick sometime with a steel cradle ,headsets were often steel early alloy ones were a revelation in the hand ,brooks saddles were heavy replaced by early horrid plastic ones then got heavier again but don’t knock the ‘vibe’ of buying a Turbo with Hinaults badger logo on it ,then there the solid lump of alloy called a quill stem and it’s easy to forget about that combo of a steel pipe within another called the steerer tube
