The picture below is of the writing on the back of my 16" f/4.5 mirror. Obviously, diameter, focal ratio, and focal length are the main numbers, but it also looks like it has the date 2/2000 which is hard to see. There are also what look like initials "JC"??? Are these all possibly markings from a previous recoating, refiguring, or just typical script from the original producer. It is believed to be an older Meade mirror.
Thanks for anyone's guidance.
