I have the opportunity to get an ancient Tinsley 5" f12 (at least I think it's f12) on its original cast iron mount/pier but can find no precedent for its value.
The scope is in just OK condition, a small clamshell chip on one element, and some overall age and wear as you can see. The mount is completely untested, the old power supply and cordage is a bit scary so I probably won't plug it in, expecting the next owner to rebuild it.
Anyone have any knowledge of previous sales or even a suggestion as to value? One report I read suggested there were only 12 of these made but with no supporting evidence. One CN ad said "Have been told Mount alone is worth $1500 w/o pedestal (rare)".
I posted on this scope a while back here:
