A book could be written for this, much depends on the country of origin, especially in the 70's and prior.

There were some mighty tight, English frame sets in the 70's and some even more extreme Dutch builders. Schroder comes to mind.

Then when one factors in the conventions of proper fit, which have changed over time, it gets really confusing.

I have an Italian bike from 1953, that aside from longer chainstays than are common now, and really long rear brake reach, could be mistaken for almost any mid 70's Italian roadbike.
