SPT - PetriColor35
Specialized technical manual by James Todd Amos for the Society of Photo-Technologists (SPT), providing comprehensive service information for the Petri Color 35 camera. This detailed guide includes pre-disassembly inspection procedures for the black standard model serial number 580344, with precise measurements of shutter speeds and flash synchronization specifications. The manual presents complete operational theory covering the film transport mechanism and wind lever-actuated shutter system. Detailed sections address the safety ratchet assembly, tooth plate screw, and drive gear components with annotated photographs of key assemblies. The document thoroughly explains the exposure meter safety switch operation, helical focusing mount function, and battery replacement procedures for compatible types (HC, National M-1C, Mallory RM 675, Toshiba TH-KC). Published January-February 1972, this manual serves as an essential reference for technicians engaged in restoration and repair work on classic film cameras, offering both theoretical understanding and practical servicing guidance.
