WWII German Artillery Sight Mount Base

Updated August 27, 2026

Produced during World War II for German artillery forces, this periscopic panoramic sight mount base displays top plate stampings reading "L.O.Nr.4" and serial/assembly number "Sr. 1343". The mount base measures 5 inches high by 4.5 inches wide by 3.5 inches deep (12.7 cm H x 11.4 cm W x 8.9 cm D) with a 2.75-inch main body housing diameter (7.0 cm) and weighs 1,281 grams (2 lbs 13.2 oz). Constructed with heavy steel and brass housing components, a vertical central mounting spindle, silvered 6400-mil azimuth scale bands, and side-mounted micrometer drum controls, the unit maintains full mechanical movement across all adjustment controls and locking thumbscrews. The top-mounted circular bullseye spirit level remains intact with its internal bubble indicator fluid present. All olive-drab green field paint and metal finishes remain unrestored, displaying age-appropriate paint chipping, surface wear, and light patina.
