Our club may get involved in a project to renovate a 1920's observatory and Bausch & Lomb 4" Refractor (~f/12) from ~1921. Anyone have or know where I can find some information on these scopes? The scope cost $750 when new. It also has the original Bausch & Lomb pier/mount/clock drive. I have searched Google, but didn't find anything.
