An exceedingly scarce photographic sample album for the groundbreaking and innovative Progressive Welder Sales Co. during World War II. The company was founded in 1935 by Johnson (b. 1896), noted Chrysler engineer and trouble-shooter who invented the first multiple-point spot welders for use in auto production, who quickly began developing and creating resistance welder machines which redefined fabrication techniques to meet wartime production demands. These extraordinary photographs show the jigs and machinists creating the necessary welding equipment in constructing tanks, tank gun turrets, extra belly tanks for aircraft, and the necessary machined parts. Also shown are the checking fixtures designed and built for the various manufacturers producing the Fairchild C-82 Packet, a twin-engine, twin-boom cargo aircraft used by the USAAF during World War II, which was also designed as cargo carrier, troop transport, dropping parachute troops, and glider towing. Also shown are mount welding fixtures for the Glenn L. Martin version of the B-29 Superfortress, jigs and equipment to properly and quickly manufacture B-29 wings, B-24 Liberator Wings, drilling gauges for Curtiss fighter planes, along with the many fabricated fixtures and welding equipment designed for Chevrolet's St. Louis plant producing DUKW Amphibious transports (Duck's) used heavily on the D-Day beaches of Normandy, and in the Pacific theatre on Saipan and Guam. Fred Johnson and his company invented scissors-type welding guns, rotisserie jigs for turning pieces under manufacture, and his multi-spot welder machines were combination hybrid presses and fixtures which sped up aircraft production in World War II by unparalleled amounts. Progressive Welder Sales Co. was very active during World War II often producing these massive thick sales albums featuring their latest innovations on resistance welding technology, all of the factory fixtures they were producing, and how they could speed up production, but we can find no institutional listings of other survivors. In 1950, Progressive Welder Sales Co. was converted over into the innovative and groundbreaking Creative Industries of Detroit, which launched itself into national consciousness by building President Truman's Lincoln Cosmo, and would go onto build the concept cars such as the FX-Atmos, Mercury XM-800, Dodge Granada, Packard Balboa, Ford Mystere, Corvette Corvair, Dodge Charger 500 and the Plymouth Superbird.
