10” f4.5 Pyrex blank #1 ready to polish.

This is a fine annealed Newport blank that I have ready to polish. It is fine ground with 9 micron Aluminum Oxide. From here I just polish with 1.5 micron Cerium Oxide. It has ~9.950” working surface to the chamfer, it is full thickness 1.8”
As I mentioned in the private message the side, chamfers and bottom are all ground as well. I am posting this to show Augustus and will set as offer pending. I’ll post another blank #2 which is in the same state. So that someone else will have a chance at one as well.
No rush, take your time look the blank over let me know.

*.* Update *.* Augustus asked me for the weight of the blank. And it is 11 pounds and 12 ounces. Unfortunately Augustus passed on the blank at this time for use in a truss design he is working on. So I will re-list the blank. And as always I can answer questions that anyone may have. Thanks.
$150.00 Paypal only, I pay fees shipped UPS need a couple of days to get this properly packaged as you caught me flat footed on this one
Continental 48 states only.
Thank you for looking
