DEACTIVATED. The MK151 canon was an important aircraft in German aircraft during WW2. The cannon was developed during the 1940s to replace the drum fed FFM 20mm cannon fitted to the Messerschmitt Bf 109. The cannon was originally developed in 15mm calibre but this was dropped and the gun was developed as a 20 mm cannon called the MK 151/20. This weapon proved very effective, being a belt fed gun especially when used with the Meingeschloss high capacity projectiles. This is an original WW2, MK 151/20mm aircraft cannon barrel that has been recovered from a wrecked German aircraft. The barrel measures 43 ¼ inches in length and is stamped in front of the chamber MG151/20 2005 and 6994. The barrel is bent approximately halfway along its length where the barrel is knurled (See photographs), rendering the barrel incapable of discharging a projectile. This damage will have been caused by the aircraft impacting the ground or crashing. This damage renders the barrel deactivated by condition. The barrel has its mountings lugs to attach it to the gun at the breech. The price includes U.K. delivery, and no licence is required to possess this barrel in the UK if retained as a part of a collection or display. D 2126
