I finished this mirror back in '03, coated by Owl, just unwrapped it and tested it. Full thickness old Pyrex, recessed back.
Must say, it's a real beauty, no scratches, nice diffraction ring, tests at 1/19 to 1/23 wave. Liquid smooth. I finish figuring my pieces with rouge.

Pardon the weirdness in the hand held photos. I use an old elbow telescope at 45 degrees and it rotates the pic. 150lpi Ronchi. Artifacts in the scope, currents from wood stove, etc.
You'll be happy with this one.

Buyer pays shipping, Paypal Preferred.
