For sale, a classic set of Mak blanks.... in the mid 80s, I attended Stellafane and spent some time at the Swap & Shop table. That year the Boston ATM group had brought a large number of unused partially finished blanks from some of their projects, this glass was selected from that lot. I took home one 6" primary blank and two corrector blanks, all perforated. These have never been handled since purchase just boxed. All are made from fine annealed optical glass which I am guessing is BK7. I've labeled each item 1,2,3 in the photos with details below.

Item 1. Plano-convex blank with 40mm core cemented in, fine ground to grit 150 or better on flat face. One shallow edge clam.

Item 2. Corrector blank with sagitta about 9 mm, 25mm core cemented in, also fine ground to grit 150 or better on both faces. This blank has the roughest edge clam of the set about 7x5mm.

Item 3. Corrector blank with sagitta about 9 mm, 25mm core cemented in, also fine ground to grit 150 or better on both faces. This blank has the largest clam of the set about 10x8mm, but very smooth and shallow.

Prefer to sell as a set, but may sell separate items for $25 each plus shipping. Take the entire set of glass for $60 plus cost of USPS Small Flat Rate box, making it $67.90, ship to CONUS only. Prefer Paypal, I'll pay fee.
