While reviewing my stash of Durst literature, I came across this interesting device. It was a display stand to show customers in a store how easy it is to make enlargements.
Functions a little like those Afganistan cameras, where the chemicals are all contained in the box.
I guess they had a monobath in the tray, but if larger with a motor base and paper drum? How dark would the room need to be not fog the paper while keeping the red Plexiglas light enough to see to focus? And no use of grain focusing device.
I used a box like this to give a demonstration to a group on Lith printing. But the paper was exposed in a dark room. We just did the processing (the interesting part) in the box for a group to see. What I thought here was unique that they put the enlarger IN THE BOX.
I think I remember a Minox demo at a camera show like this when I was a kid. Don’t remember about trays, but I do remember the experience- it was like seeing magic. My Dad had a lot of interest in the Minox line back in the sixties, but he never got one.
