Manufactured from 1932 until the present, the Bofors 40 mm anti-aircraft gun was designed in Sweden and produced by many countries. A very successful design that revolutionized air defense and was used on towed ground mounts, fixed positions, ships, and later armored vehicles and aircraft. This demilled gun was produced by Chrysler in 1943 and includes a feed chute cover. The M2A1 carriage as found on this example was an improved version of the M2 with faster rates of elevation and traverse. Rate of fire was 120 rounds per minute. Chrysler manufactured approximately 60,000 guns and more than 120,000 gun barrels during WWII. Consignor research is included.

The mount is complete and well restored. The gun breech is demilitarized. All the other functions of the gun and mount are functional including the elevation and traverse. The stabilizers work and lock to make a very stable platform.
