I have recently purchased a Full thickness F6.3 12.5" mirror. I was told the mirror is Pyrex. It has a sticker on the back that says Beral coatings (90%). It is in great shape with no chips on the reflecting surface.

I am looking for a 12.5" F5 mirror about 1.5" thick to build a lighter weight telescope as I have to travel in order to reach dark skies. I will also sell for $400.00 + Shipping and insurance. I will travel 100 miles from Knoxville TN to deliever or Trade. Email me with Questions.
I have had alot of inquires as to the history of the mirror. Here is all I know that is not above. A friend of mine who makes telescopes, mirrors, and refractor lenses, says it is a good mirror. The mirror was made by an individual with the help of my friend. It was coated by a company from Illinois called Dudley LeRoy Clausing.
I have included some pictures. One is the Coating sticker, Two are the mirror front, the last is the back. They are not very good but they were the best that I could do.
