I've had good luck checking with old print shops.... 2 of them have given me process cameras....free!!!!! they were happy to have them hauled off.... the largest one has a 10 foot rail so it takes up alot of studio space, oh yeah it came with a goerz red dot artar too!! I converted the smaller one (14x18!!)
into an enlarger.
so check with older print shops, most have converted to ...(gasp) digital so the old stuff is in their way!
