I have four boxes of very oddly sized fuji black and white sheet film. The acros in 6.2x8.8cm and the neopan 100 in 8.2x11.8cm are sealed, the larger boxes are open if my memory serves me correctly. No idea what to price these at so make me an offer if you want any of it. I will also consider trades for any other film in any normal format.
The 16x21cm (6½x 8½") is British Whole Plate size, the 11x16 cm (6½x 4¾")is British Half Plate and the smallest (2½ × 3½") is sixth plate size. Not sure about the remaining size, it isn't a "plate" size. Might be the nominal "3x4" Speed Graphic size.
