GRAFLEX - Graflex FPS SeriesD USN ServiceNotes1949
Comprehensive service notes issued by the U.S. Naval Air Technical Training Unit in November 1949 for Graflex Series D large-format cameras (4x5 models). This workshop manual delivers detailed disassembly and reassembly procedures for focal plane shutters and escapement mechanisms, with specific guidance on spring tension settings and shutter plate alignment critical to reliable operation. The troubleshooting section systematically addresses common field failures: defective escapements, curtain binding, light leaks, mirror mechanism faults, and focusing system problems. Maintenance procedures cover preservation of precision optical components including first-surface mirror coatings, ground glass surfaces, and lens elements. Complete instructions for 4x5 coupled curtain-blind shutters and associated film magazine assemblies include step-by-step diagnosis and correction of emulsion wear, broken springs, and assembly defects. An essential repair reference for military equipment technicians and restoration specialists maintaining Graflex large-format camera systems.
