Want to Buy Azo paper wanted

I am looking for older stocks of Kodak Azo papers. I prefer the vintage that used color coded rectangles such as in the image attached--green refers to Grade 2, blue to Grade 3, etc. The label will also say made in USA or printed in USA. I am primarily interested in grade 2. I will pay a very good price for these papers. I am looking for 8x10 papers or something larger that could be cut down to 8x10.

There is some sized 4x5 on eBay right now. I think 500 sheets.
