[Atmswap] Optical Glass

[Jacob R Lauser]

Greetings!

I had spoken to someone off list several months ago about swapping some
optical glass for a project I am building, but nothing came of it. Now
that I'm back on track with my project, I still need to get ahold of some
F2 or F4 and some BK7 and I was wondering if anyone had blanks to spare in
the range of 14.5-16 inches. I have KF4 blanks that I'm willing the swap
in exchange. They're about 16" in diamter and 2+ inches thick. Thanks...
