Tim, you might be interested to hear that I found Tinky's sister 'scope, C8 #0136, the guy says ;-
"I have inherited an very old C8 orange tube. It came with several boxes of accessories - this is as close to ground 0 for C8's - Serial # 0136. Documentation in the box dates from 1970 and '71. So I believe this was made in 1970, when their production optics were all hand figured and matched. The mirror looks in good shape, but the corrector plate is dirty with some small mold spots on the inside. I airbrushed and then took it to tryout on Saturn last night. I think the optics are very likely superb, focus test is perfect. Saturn looked sharp, given its low altitude, but definitely the view was dim and affected by the dirt on the corrector. Hope this helps with the registry that you are putting together. Any advice on how to proceed with restoration is appreciated..."
Note the dates.
