COMPUR - Compur Shutter Construction

Comprehensive technical service manual detailing the construction and operation of Compur and Compur Rapid shutters—among the finest interlens shutters manufactured for precision cameras. This workshop manual traces their development history as monopoly products of Deckel in Germany, while examining competing designs including the Kodak Supermatic. The guide provides in-depth analysis of the internal mechanism: thin steel blades, actuating ring, and the timing system governing shutter speeds. Flash synchronization receives detailed treatment, with comparisons to the alternative operating principles found in Prontor II and Klio shutters. Coverage extends to the fully synchronized Compur Rapid (offering both X and M sync contacts) and the Prontor SV, addressing both flashbulb and electronic flash synchronization techniques. Extensively illustrated with technical diagrams and sectional views throughout, this repair manual is an essential reference for anyone maintaining, servicing, or understanding the precision mechanics of these shutters as used in classic camera bodies. Ideal for camera technicians, restorers, and enthusiasts working with German and European camera systems.
