WWII U.S. Signal Corps Developing Equipment PH-253-C (1944) – Complete with Case, Rare Film Processing Unit

A very scarce original U.S. Army Signal Corps Developing Equipment, Type PH-253-C, manufactured in 1944 by The Morse Instrument Co., Hudson, Ohio.
This portable developing unit was specifically designed for 16mm and 35mm motion picture film, allowing the Signal Corps to process, develop, and view film in the field during World War II.

Historical Significance:

Film was a vital tool for the U.S. Army during WWII. Units like the PH-253-C allowed Signal Corps technicians to quickly develop and review training films, reconnaissance footage, and propaganda reels right in the field. These portable developers were often paired with Signal Corps projectors such as the PH-222-A, making it possible to shoot, develop, and project film within hours.

Collectability & Value:

This equipment is far rarer than the projectors themselves and seldom appears on the collectors’ market. It is a must-have for advanced WWII Signal Corps, film, or communications collections.
