The Speed-O-Matic Corporation was a camera maker based in Boston, Massachusetts, U.S.A. . In 1948 it manufactured the Speed-O-Matic bakelite "instant" camera or film packs. Every exposure with that camera had to be prepared by unloading the film pack, flipping it, and reloading it. After every second exposure the pack with the exposed film sheets had to be transferred into a separate development tank. In a process with a succession of four chemical solutions to be filled into the tank and refilled into bottles an "immediate" processing was possible. Like the "pseudo-TLR"s this camera should be classified as "pseudo instant camera".
