I have for sale a Horseman view camera with the L-shaped standards and expandable monorail. I believe that's called the 450 EX. The camera is in excellent condition both mechanically and aesthetically. All controls operate smoothly. There's just a small amount of finish wear on the "ears" of the back where you pull it out to insert a film holder. There's also a very small nick in the finish on the right rear of the rail (see photo). I'm asking $300 for the camera, which does not include shipping. Included are three lens boards. If you shoot film, you might be interested in the 4x5 film holders and Polaroid 545 back I have that can go with the camera. Photos are below. If interested, please PM me, or email at firstname.lastname@example.org Thanks for looking.
