A couple of very old and quite unusual Kodaks:
-the most tiny camera ever made by Kodak, the 00 Cartridge Premo. It used 35mm film way before the commercial Leicas, in 1916. But this 35mm film way like a miniature 120 format, without perforations and with back paper. The camera works, but lacks one of the spools, so it could be difficult (but not impossible) to take pictures with it again.
-a No.1 Panoram Kodak, that still works, more or less.
