Ok, finally I set it up on a table in the basement and grabbed a couple quick shots with the little PnS. See it did happen!
The carriers are 35mm, 4x4 (127), 6x7, 4x5.
The paper safe has a bunch of wrapped paper but it is cracked pretty badly. Hopefully at least some of the paper is usable. I'll get to find out in a couple months when I can actually print.
Now, to start looking for a 4x5 camera.
