Horseman SW612
I have recently tested a Horseman SW612. It’s a nice camera if you like the superwide 120 rollfilm format. AFAIK it was first introduced in 1999 by Komamura & Co. The lens is a Rodenstock SW Apo-Grandagon f4.5/55mm and with the Copal 0 mount allows up 1/500sec.
Focus is by guess-timated by a straight helicoid. The view finder is clear but not coupled to the body. Weight is approx 1400 g including finder and safety rails. It’s definitely a portable camera and I would have kept it if the helicoid wouldn’t be so tight that I couldn’t even move it.
There is also a professional version of the SW612, that allows lens to rise & fall of 17mm, and side shift of 13mm, so I would definitely go for the professional version if you are looking for a used camera.
