With Satin Snow no longer accepting new orders (at least that's what the website says), are there any sources for 8x20 ground glass? The Canham site implies they have some available but I haven't checked with them directly, and a Google search doesn't turn up much.

Actual overall size is not important as I'm building a back for a Kodak D2.

Does anyone use (2) 8x10 glasses simply mounted next to each other. Opinions on that approach?

Thanks
John
