I bought a "lot" of vintage equipment off Craigslist from a lady who was moving and she had some of her ex-boyfriend's camera equipment in the garage. She called this item a "foldy camera thingy". My friend picked it up for me today and I will be getting it Sunday (I live in the country), but sent me these pictures. This is one of four items I got. Anyone shed some light on what this is specifically? I currently shoot MF and 35mm and this didn't look like either of those, so I thought I'd post it here.
It is a Leica bellows with a reflex housing, possibly a Visoflex. Sorry, I'm not up on Leica gear, so I can't tell you which versions the bellows and Visoflex are. But since they both have bayonet, not thread, mounts they're probably for Leica M. Not large format, 35 mm.
You're more likely to get a good answer if you post y'r question in the rangefinder section. That's where Leicas live.
