We have found an 8.5″ diameter, 72″ focal length mirror at my local society, and we don’t want it. Is it worth anything? It has some blemishes in the silvering and there is a small secondary with it, which we presume goes with it, but have no idea. We are not even sure of its history. I think it was passed to us when one of our members passed away.
Thanks.
