A good example of this iconic Anti Aircraft guns shell casing.
The Bofors gun, is an anti-aircraft autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well some captured systems being used by the Axis powers. A small number of these weapons remain in service to this day, and saw action as late as the Persian Gulf War.
The gun fired a 900 g (2.0 lb) high explosive 40 × 311R (rimmed) shell at 2,960 ft/s (900 m/s. The rate of fire was normally about 120 rounds per minute (2.0 rounds per second)
This shell has not been polished and is in original condition.
Irregular dents to the rim but for its age it is in good condition.
