Want to Buy WTB: 8x10 wooden back....

hello,

I working on a modification to my 8x10 Cambo and need a wooden 8x10 back which I want to modify to accept inserts so that I can get 8x8 and 7x7 images for contact printing.

Let me know what you have and the cost of postage to Canada, H4A 2R2.

Thank you!
