Description
40mm Bofors L60 Compression Spring, A050, P/N 6198369
The 40mm Bofors L60 Compression Spring, identified by P/N 6198369, is a U.S. ordnance service component associated with SNL group A-50 for the 40mm Automatic Gun M1 and its gun carriage system.
The package identifies the item as a spring, compression and carries the stock marking A050-61-98369. Later logistics data cross-references the part to NSN 5360-00-597-0385.
Historical Significance
The Bofors 40mm L/60 design was widely used as an antiaircraft gun system during World War II. The U.S. Army standardized its version as the 40mm Automatic Gun M1, used with the M2 and M2A1 antiaircraft gun carriages.
Service parts for the gun-and-carriage system were organized under SNL A-50. The July 1954 package date places this example in the postwar U.S. military supply system, when 40mm gun materiel remained supported by stocked replacement components.
What This Item Is and Does
The 40mm Bofors L60 Compression Spring is a cylindrical helical spring designed to resist force as it is compressed and return stored mechanical energy as that force is released. It served as a numbered mechanical component within the A-50 gun-and-carriage parts system.
Logistics specifications identify this spring as a steel, right-hand-wound compression spring with a cylindrical form.
