I have been trying to find one of these that works and isn't ridiculously overpriced for a while.
I may have finally done it...
It seems to work, though the light seals are a bit sticky, and the film transport doesn't like the roll of 36 I'm currently using to test it (what was I thinking?) so I have to be slow and gentle to advance the film.
Impressively, however, the flash goes up and down, and everything seems to be working.
I had one years ago that basically fell apart in my hand, so I know they're fragile, but I liked it a lot when I had it...
