I picked up Kodak 2d 8 x 10 recently and it came with a 5 x 7 reduced back on it.
I am wanting to do 8 x 10 format for now so I was checking to see if anyone had an 8 x 10 back lying around. I could potentially make one but lack the hardware., ie springs etc required.
I can also make my own g-glass.
Let me know if you have one available.
