Torpedo cameras don't come with lens boards but one could adapt them to use boards. Robbing the front bit from a 3x4 Graflex parts camera should do nicely. The flat part of the front is 97x113mm and the factory hole size is 89mm. These have no bellows but one could add bellows or just use a focusing helicoid which I also have for sale/trade. Taking the latter route would necessitate the use of a lens of 135mm+ unless it's a bit recessed into the body. The rigid bodies are 127mm deep from the outermost front to the film plane so if you want to shoot with lenses wider than approximately 125mm using one of these bodies then you'll need to adapt a recessed lens board. I have the perfect recessed board for this... if mounted inside the body will give you an extra 40mm of depth for a net minimum depth of about 87mm. You should be able to use a 90mm at infinity with that combination. Using a 90mm lens on this film format is similar to using a 20mm lens on a 135 format camera... speaking strictly of length of the diagonal.
These torpedo backs are a bit wider than typical 6x17cm... being 5.7x18.6cm. Any lens with 195mm or greater coverage will fill the film corner-to-corner. The recessed lens board I mentioned above is large enough that I can still see the side aperture scale of a 90mm SA but you might need a mini flashlight in some lighting conditions. It's also large enough that I can get my fat fingers in to adjust the lens. BTW, I have a nearly mint late model 90 SA for sale too.
One thing about these gov-surp torpedo cams is that they have several bits on the body that are unused for typical photographic use and those pieces aren't very pretty. It's best to have those machined off. It's a simple process so it shouldn't cost much especially if you have a friend who works at a machine shop. Once cleaned up these make very fine-looking cameras.
