!!! TRADE !!! #### 12 inch THIN EDGE PYREX Telescope Mirror Blank ####

Description

I would like to trade my blank as described below, for a full thickness, full diameter (2 1/4" x 12 1/2") Pyrex (or the Borofloat or Supermax glass) mirror blank or mirror. It can have small chips on the edge.
My blank is generated for an F/6. Has a defect on the edge BUT does not go into the clear aperture. Also has a fracture on the bevel but would be invisible when polished and would not effect the figure when finished. Please refer to photos.
