Rochester Camera & Supply Co. Stereo POCO
The Stereo POCO camera was a typical turn of the century cased camera design. I tend to think of this as the third basic design evolution. Early cameras were of the sliding box type, then came folding designs with leather bellows, but their components were still exposed when the bed was folded up. Cased cameras were the norm for over 50 years. It took modern 35mm SLRs to unseat them. By changing the lens board and removing the internal septum, the camera can be converted for shooting regular 2D photos.
