Anyone know where I can source the 10"x12" Paterson developing trays outside of the UK? I had a set of 3 from when I lived in England that came over with me. However, they have seen better days since I startd using them for wet plate. They are just a little bigger than 8x10 trays and fit nicely into my darkbox, and make a perfect match for up to 8x10 plates providing a nice area for developing and washing plates. I seem to remember that there was also 9 1/2" x 11 paper available at one time. I think these trays were meant for that. Paterson still sells and markets the 10x12 trays, but for whatever reason, they are unavilable in the US. This 10"x12" size tray is also perfect for lith printing 8x10 paper, by providing more developer volume... Next size up over here is 12x16, and is just too big for my darkbox.
