I purchased an old 10" f6 fiberglass tube that looks like an old Cave scope that someone put a newer focuser on. The main pyrex mirror looks good but the coating is a little faded. The word HALL is scratched on the back of the mirror but there are no other marking except a Hard Beral Coating sticker by Dudley Le Roy Causling of Skokie IL. The words 10"D and Made in USA are also on the bottom of the glass and are part of the mold. The side of the mirror has been coated so I can't see any marking there.
Can someone give me any information on this mirror and any coating suggestings. I was going to use Spectrum Coatings and put a 95% coating on it and the secondary.
Thanks, Allen Stuart, FL
