PRONTOR - Moriarty Klio Prontor II Tutorial

This comprehensive repair manual provides systematic instructions for complete servicing of the Klio/Prontor II Gauthier shutter mechanism used in Zeiss Ikon Contina 1 and Ikonta 35 cameras. The workshop guide breaks down disassembly and reassembly of this intricate shutter assembly with step-by-step clarity, covering removal of the front cover plate, extraction of the self-timer mechanism, separation of shutter blades, and aperture mechanism disassembly. Detailed technical photographs annotate each stage, illustrating spring positions, component relationships, and precise configuration of the shutter ring assembly with its five locating screws. The guide emphasizes critical points that determine successful reassembly: correct positioning of the aperture ring to access mounting screws, identification of the specialized pair of retard escapement screws (non-interchangeable despite similar appearance), and proper blade orientation during reinstallation. Complete component identification covers the self-timer mechanism, retard escapement, control levers (cocking, release, and bulb), flash lever, and all associated springs and fasteners. An essential service manual reference for camera repair technicians and vintage camera restoration specialists working with German rangefinder equipment.
