BOLSEY - bolsey camera ground b2

Complete factory documentation for the Bolsey Ground Camera 35-MM Model B-2, a professional rangefinder camera from 1951. This service manual comprises two sections covering everything needed for overhaul and repair. The general overhaul instructions (T.O. No. 10-10BC-6, April 1951) begin with full technical specifications: 44 mm focal length lens, aperture range f/3.2 to f/16, complete shutter speed data, and rangefinder performance details. The core of the manual walks through systematic disassembly of every assembly—camera body, shutter and lens mechanism, rangefinder, viewfinder, back and top covers, film advance, and gear train—with step-by-step cleaning and inspection procedures that assume hands-on work. Reassembly guidance and functional testing protocols follow, allowing you to verify proper operation after overhaul. The second section serves as the parts catalog (AN 10-10BC-7, April 1951), providing group assembly breakdowns, complete component nomenclature, and a numerical parts index. A detailed exploded diagram identifies each part's location and relationship, essential for ordering replacements or understanding how assemblies fit together. Invaluable for repair technicians, camera restorers, and serious collectors undertaking maintenance or restoration of this precision 35mm instrument.
