Antique pair of World War II era 20mm MK2 Oerlikon inert display rounds, both dated 1943 and head stamped "20MM MK2" on their brass cases, consisting of one High Explosive round manufactured by Bridgeport Brass Co. of Bridgeport, Connecticut, and one Tracer round manufactured by A.S. Campbell Co. Inc. of Boston, Massachusetts. The Swiss designed Oerlikon 20mm autocannon was one of the most widely used anti aircraft weapons of World War II, mounted on Allied naval vessels, aircraft, and ground installations to defend against enemy air attacks, and these rounds were produced in enormous quantities by American manufacturers to meet the insatiable wartime demand. The High Explosive round retains its original white painted projectile with a black tip showing significant age related paint loss and patina, while the Tracer round features its original olive drab projectile with stampings including "MK7" and "T.B. 12" still visible on the body. Both rounds seat into matching brass cases with copper drive bands and display beautifully together as a study in the two primary 20mm projectile types used during the conflict. Bridgeport cartridge measurements are OAL 7.18in CL 4.35in MW .78in A.S. Campbell cartridge measurements are OAL 7.06in CL 4.35in MW .79in
