I stumbled on these images and wondered what camera made them. Image is dated 1934 by sarin, Bull of the Woods Lookout, Oregon.
Is a it a specific camera used by the USFS? is it a film holder or insert? is it a custom mask specfic to the lens and camera?
very neat! and with that horizon line too...

Turns out the camera was developed by William "W.B." Osborn, from Portland OR and the USFS:

Aha! information on the camera, and a link to more images of the "osborne photo recording transit" aka Osborne Camera itself.

And a little bit more on the camera and another invention by W.B. Osborne, the Fire Finding device:

What is the print size?

According to NYforestrangers source: " 6" X 14" prints " were made, this is in the 1930's, I imagine a similar negative size of 6x14 inches was probably used for contact printing. The image ratio is about 6x16 on the samples above, with the borders the negative has about a 6x14 ratio. To me a 14'' long negative is a bit surprising and longer than I would have suspected, but the cameras are large and heavy (75lbs?!). I have yet to see a print or negative in person.

The Osborne Camera Manual (http://www.iamwho.com/osbornes/latest/camera%20operators%20manual%20doc.pdf) states Roll film of 5-15/16"x100" were used to capture 6 (six) exposures per roll which would be about 15'' long depending on the image's spacing and leader length.

I wonder if Vaughn ever saw one of these.
