Interesting... Back then in the 50-60'ies when grandpa was a kid, there was no such thing as a "classic scopes" hobby, -- no antique sales, no flea market finds (and certainly no scopes in MY grandpas attic!) Oh yes, a few pre-war Zeiss and Merz refractors from Danish observatories somehow ended up in the hands of amateurs, but that was an exception to the rule.
We bought our 2-3" scopes (aka. refractors) new from German or Japanese import (Zeiss, Unitron). The criterion was a good stable mount and a Dawes "diffraction limited" lens. A few ads for optical imports were in the newspapers, and astronomy news were communicated through one scientific journal for Scandinavia, -- mostly covering hard astrophysics but sometimes also including a review or observation report by a knowledgeable amateur. Luckily we had Patrick Moores books written for amateur astronomers.
A few hardcore amateurs bought large 4" Unitron refractors and installed them in private observatories. No collection, restoration, comparing, competing. Focus was not so much on the tools of the trade as on careful observation and sometimes even scientific research, mostly in stellar and lunar astronomy.
This all changed in the 80'ies. Then came the Vixen Newtonians and Fluorites. Then came the Celestrons, then came the Meades. Then came the Dobsons… Ahh well, it's all progress, as Mark Knofler sang (https://www.youtube....h?v=Q1Wp2ASqyxI) :
He built a cabin and a winter store
And he ploughed up the ground by the cold lake shore
And the other travellers came walking down the track
And they never went further, no, they never went back
Then came the churches, then came the schools
Then came the lawyers, then came the rules
Then came the trains and the trucks with their load
And the dirty old track was the Telegraph Road
Then came the mines, then came the ore
Then there was the hard times, then there was a war
Telegraph sang a song about the world outside
Telegraph Road got so deep and so wide
Like a rolling river
