Finally picked it up. Considering ground glass replacement somehow. Biggest problem is getting film holders.

Also got some Europan 200 ISO 9X12 film second hand.

Any possibility of DIY solutions to film holders? Such as using a light proof cloth cover and insert a plate with the film mounted somehow?

How about developing? Can I process 9X12 film with film developing chemicals as though I were developing paper (in complete darkness) in paper trays for example?
