As title really, Just purchased my first 5"x4" camera and do not have any means of either exposing or processing 5"x4" film so am looking for a 6x9cm rollfilm back to fit a Toyo C Monorail camera. Please contact with condition and price.
I've got a couple of 5x4 film holders I can post your direction. Development can be done in a Paterson tank, google for the "taco method" - This should get you going until you can find/fund an alternative.
