How cool! It falls right into the time period that I proposed in my previous post based on the Unitron finder.
"So if that is the original finder, the OTA had to have been constructed after around 1967. Now the question becomes- Was the mount original to the scope?. If that too is yes, then there should be someone here who remembers them, assuming they were manufactured."
