This is a scarce unfired British WW2 1944 dated 77MM H.V. (High Velocity) (76.2 x 420R) Armour Piercing Capped Ballistic Cap/Trace (APCBC/T) round for the British Comet tank. This gun enabled the British Comet tank to upgrade its main gun from a 57mm, 6 pound, 7 cwt gun to a high velocity 3 inch (76.2MM) gun that was developed by Vickers in WW2, The cartridge case being based on the 3 inch 20 cwt case which had the same dimensions and was shorter than the 17 pounder case. The 77mm HV gun fired the same projectiles as the 17 pound gun used in the Sherman Firefly, Archer converted from the Valentine tank, Achilles and the American M10 / M10A1 tanks as well as the 17 Pdr towed anti-tank gun. The capped round was introduced to stop the standard armour piercing projectile shattering when hitting face hardened armour plate by the addition of a soft iron cap soldered to the top of a armour piercing projectile. This round was ballistically inefficient due to the flattened nose and was soon replaced by the streamlined Armour Piercing Capped Ballistic Cap/Trace (APCBC/T) projectile.This Armour Piercing Capped /Trace (APC/T) round is headstamped on the brass cartridge case 77MM I LOT26 ECC (Elswick Cartridge Company) 1944 (1944 date) SR (Cordite Reduced Charge). The APC projectile has two copper driving bands and the top band is stamped 2 2 and a crowfoot. The price includes UK delivery and no licence is required to possess this inert round in the UK if retained as part of a collection or display. O 1917 £975.00
