Just in case the feeding frenzy hasn't started yet....
If it was a 3" i would jump...
if you ever saw a 3" equatorial for $600 I think you would be standing in line with the rest of the jumpers.
Even $1200 i would jump if it was a pre 1970.
Still too cheap and you know it
Depends. I would go much higher for a early 60's made 3" Unitron %100 complete and not a mix mtach of older and newer parts. Seems most of these scope are missing parts, beat up, no case's and mix matched parts.
You talking about scopes or us
