Acquired this C5 F/10 1250mm Telephoto from a gentleman who originally worked at Celestron. Serial "1 287 7". Primary Mirror marked "3361 T". Had a sticker that has came off with age.

Just a quick post to thanks to Max Lattanzi and baelyn for the details on their C5s which I added to the C5 Registry back at the start of November and bumped to version 7.1.
Thanks also to Max for pointing out that I had his other C5 # 4 3359 7 (end of 1977) within the list of those C5s having the 6 1/2" base and sand cast mount (holes in the forks) whereas it has the larger C8 base and diecast mount (no holes in the forks). This prompted me to go back and check some of the other scopes from around that period and I see that I made an error in assuming that the diecast mounts came in at the beginning of 1978. Having looked back at some of the other pictures, the change over came in the third quarter of 1976 – the C5 that CHASLX200 had (serial 3 2275 6) was one of the last sand cast ones and eTourist’s C5 (serial 3 2413 6) being one of the first die cast ones.
baelyn’s C5 telephoto has an interesting serial number as it does not fit in with the general run – whether this is because Celestron used a separate series for the telephotos (those C5s which were sold as OTAs for use as a guidescope appear to follow the same sequence as the C5 fork mounted scopes) or whether it was because it was originally made for a gentleman who worked at Celestron (there are a couple of instances of C8s made for Celestron employees / dealers having unusual serials) I don’t know.

I've updated the C5 Registry to version 7.2 to include your new find.
