Does anybody here have a sheet of 12x20 film that's been, for whatever reason (other than punctures, tears, or crumpling), ruined? A friend is building a film holder for a home built camera and needs a sheet to check the dimensions and test loading in the holder during development and building. He'd also appreciate an 8x20 and 11x14 sheets if anybody has those, for reducing film holder construction. Please let me know; I'll cover shipping and any other costs you might have (a mailing tube or whatever). All we need is a nice flat sheet that hasn't been damaged in any way, except obviously for the photographic content. Brand or type shouldn't matter so long as it's of the real commecial sheet dimensions.
