PRONTOR - Moriarty Klio Prontor II Tutorial

This comprehensive technical guide documents the complete repair procedure for the Klio/Prontor II Gauthier shutter mechanism found in Zeiss Ikon Contina 1 and Ikonta 35 cameras. Author Richard Moriarty provides systematic instructions for disassembly and servicing of this complex shutter assembly. The guide includes detailed identification and location of all major components: self-timer mechanism, retard escapement, control levers (cocking lever, release lever, bulb lever), flash lever, and associated springs and fasteners. Step-by-step procedures document the removal of the front cover plate, extraction of the self-timer mechanism, disassembly of shutter blades, and separation of the aperture mechanism. Critical attention is given to essential details: the correct positioning of the aperture ring to access mounting screws, the specialized pair of retard escapement screws (which are non-interchangeable despite similar appearance), and proper orientation for reinstalling shutter blades. Annotated photographs clearly illustrate each stage, showing spring positions, component relationships, and the precise configuration of the shutter ring assembly with its five locating screws. An indispensable reference for camera repair technicians and vintage camera restoration specialists.
