Medium format stereo

I think the frames are for 6x6 slides or contact prints and look rectangular due to the perspective of the photo.

Ugh, I think you're right. No question a 6x9 landscape viewer would need prism lenses, but those weren't that uncommon back in the day.

Besides "Sputnik", what where the last stereo medium format cameras manufactured?

I think the 3D World TL 120-1 stereo camera fom China is manufactured currently.

Back in my photo above is the one from Rollei for the Heidoscop according to Claus Prochnow’s RolleI Report 1, available from 1929 to 1938.

hey guys, I just managed to 3d print a roll film back for the Heidoscop. It works like a charm! Is perfectly light tight even with the back continuously open.
I spend more than 72hrs on the design improving it in 24 design iterations. The design can be bought here if you'd like to make your own version of it:

cheers!

Heidoscop 120 roll film back (6x13)

This set of models is meant to make your own unique 6x13 roll film back for the heidoscop camera. Most of these camera's were equipped with plate backs and the free availability of 120 film makes the camera easier to use. This back has gone trough 24 design and print iterations and has been...

This looks cool! Where can we see some sample photographs or your design in action?

I recently was taught how to do the cross-eye 3D technique and I suddenly want to take medium format stereo pictures. A cursory googling shows me there is a Russian purpose built camera to do this, and a few ancient plate film cameras from Voigtlander and F+H. For any of you folks in the know, are any of these good options? Or is home-brew a good idea (i.e. strap two TLRs together)?

The Sputnik is a pretty good performer -- i have one and enjoy using it. You should flock the interior to cut down on internal reflections, and it takes some fiddling to match the f-stops of the two lenses which, because of the way they're mounted and linked, can get out of synch.

Another option is two slr cameras with the same lens -- two rolleicords, for example, both with 3.5 tessars. I mounted them on a single bar and bought a double cable release which was easy to synch between the two cameras. Kind of a heavy rig, but good.

Finally, there's the original Rollei stereo camera, the Rolleidoscope, which uses 120 film natively and is a handly little shooter, very nicely made. The slightly earlier Heidoscope uses or plates or an alternate roll film back, which is amazing if you can find one, it uses 120 and works wonderfully.

I saw a video the other day about a 5-lens 6x4.5 lenticular stereo camera. Yep, two shots on a roll of 120 (220 capable). Very quirky camera, not many made, fifty years old...

Here's that article:

Has anyone seen the manual for this six lens, medium format camera?

YouTuber Jack Joy has put out a call for information on a seemingly very obscure film camera.

Based on the video, he managed to get enough information to run a roll of film, but one of the shutters is wonky and he isn't impressed with the results (at half a roll plus processing and scanning and significant photo editing time per frame). Seems to me that one of these in fully working condition might be a nifty novelty, but you'd need 220 film (= 5 exposures per roll) to really be worth hauling it around.
