Jon, great idea and congrats on the race! Oh, and the award-well that speaks for itself. If you could include my Cave mirror to your list maybe it would be helpfull. I had previously stated that my mirror was 1967 but after doing some research and with the advent of your most generous offer to record these mirrors my serial number coincides with the date(s) already listed and it is dated Oct, 1961 and not as I erroneously previously stated 1967. When I had first looked at the mirror I mistook the 1 for a 7 but since that time and after closer inspection and research it is indeed a 1. The info is in cursive on the back of the mirror and IIRC looks to be in the same hand as Lews. My serial number is M 2004. Figured by Tom himself-I don't know? Another reason to make me think 1961 vs. 1967 is the Pancro label on the back has only the two numbers - 39- for the mailing code. The USPS did not start using 5 digit zip codes untill 1963. One bit of trivia I have ucovered is there is a couple of dates thrown around as to when Alika Herring worked for Cave. According to one source Tom Cave himself said Herring left the first time in 1959 but another two sources, one of whom worked at Cave, said he left in about Oct. of 1961. Could he have done the final figuring of my mirror as it has been said he did the final figuring of all Cave mirrors when he was there? I won't go there,yet! This thread has got me even more excited about my 6 inch mirror and I will dig it out and get you a picture so you can accurately record it. Thanks Jon!

Thanks Dan, whenever you get around to it, no rush.

Your swapping around sounds like the right way to get the components in the best places. I was surprised to find my 8" f/8's pier tube was taller than my 10" f/6 (25.5" vs. 22"). But I shouldn't have been surprised as the tube on the 8" is 66" while it is only 62" on the 10".

Wow what a day, a caveman award and a winning car, congrats. I am the current owner of the mirror you list being owned by Greg Stone. Included is a photo for additional info. Not visible in the photo the year is 1977.
Great idea and thanks for committing the time to do it. Very interesting information on these excellent scopes. Present owner of this 8" light weight deluxe- Gerald Elkin

Thanks Gregg. That fills in a little bit more of the gap between the early mirrors with no year in the serial number and the ones that did. That's very cool that the registry helped indicate that it is really 1961 and not 1967, I love it! Is the focal length marked on it?

I wonder what the MC prefix means? That's a new one. Hard to say about Alika Herring figuring the mirror. We need more direct information from the people who were there at the time. I have also read that Mr. Herring left in 1961 and returned in 1970.

Another update: I found an obituary of Tom Cave Jr. from the British Astronomical Association that quotes a former Cave employee, Dick Norton, as writing that Cave made 53,000 mirrors (not 83,000) and 15,000 complete telescopes.

Jon, Glad you did not use the actual one from BAA which is copyright protected! And yes, the focal length is inscribed 48" + L - F/8 .

I think it would have been OK anyway as they were quoting Mr. Norton from an article he had written about the history of Cave for the August 1994 Sky & Telescope. But I guess that would have been copyrighted also. I wish I had a copy of that article. Man, I need to pony up for a set of those S&T DVDs.

That's funny, I have been looking for that same article! The early history of Cave!

That's a VERY GOOD article and makes it worth buying the S&T DVD set worth it in itself! I haven't read or found any history like that in the article anywhere else.

Please let me correct myself yet again. My eyes just ain't what they used to be! After even closer inspection with every magnifier in the house my mirrors serial number is indeed M 2004 and not MC as I stated in the above thread. It is a VERY cursive M and kind off has a tail on it so in just looking without any help I saw MC. I apologize and have corrected it in the post above. Maybe because of the age or the fact that this info is inscribed very lightly on the back of the mirror it is VERY hard to get a good picture. I hope this will count!

No worries Gregg, that's good. I see what you mean about the M. On these early mirrors the inscriber seems to want to do the engraving with a certain flair.
