I have an inexplicable love for 20th century American-made cameras. Maybe it's the underdog syndrome, as American cameras as a group are ugly and often unloved (yet ironically incredibly popular in their day). I finally saw a Univex Mercury CC with the 35mm f3.5 Tricor lens at an estate sale at a price I couldn't resist. It seems in pretty good shape, the shutter fires, lens unscrews, focus works, but of course, it doesn't take standard 35mm film cartridges. There are ways to load film in the darkroom, so as soon as I can, I'd like to run through a roll. I wonder if anyone has designed 3D-printed replacement cartridges.
