The box I have doesn't have a brand name on it. If you Google "x-ray duplicating film" you will get several sources. I have not seen the film that Photo Warehouse sells but I expect it is similar. The film comes in a variety of sizes.

As I said in my previous post, I got mine from ebay. I really looked out - no one else bid on it so I got it for the opening bid of $2.50 for a 100 sheet box of 8x10.
Thank you Dan, I have all the missing pieces in place now.
