This last group consists of miscellaneous odds & ends that didn't seem to fit anywhere else. The ends don't come much odder than the USAF 5-481 above, a twin-lens, horizon-to-horizon aerial reconnaissance camera. It takes two 9x9" negatives at a time on 9.5" roll film. The 6" f/5.6 lenses each cover 90 degrees and are skewed so that each exposure covers a 90 x 180 degree rectangle. I used it as a night stand.
