No. 2 Folding Cartridge Premo

Uses 120 Roll Film. Apeture speeds of 1, 2, 3 and 4. I'm not sure what the f stop translation is, I am guessing it's f8 for 1 and f64 for 4, with the other stuff in between. Maybe f16 and f32?

I am trying to shoot a roll of 120 through here. Time will tell if I get it right.
