INERT DEACTIVATED. This is a scarce British Naval mark 1 brass and steel weighted drill round for the 40mm British Bofors QF 40 mm Mark I gun (40 x 311R). The gun was developed by AB Bofors of Sweden and the 40mm version was adopted by the British just prior to the start of WW2. This is an early British made drill round for the British Bofors gun. The round is made out of a turned brass body with a steel nose and base attached and riveted through to secure them. This round replaced the wood and brass mark 1 round which was not found to be durable in service due to the harsh action of the Bofors gun. The round is weighted internally to resemble the complete round. This profile enabled the round to be fed into the action when gun drill was carried out. This drill round is headstamped 40 M/M N1 (Naval mark 1) DRILL a crowfoot DIFCO 1953 (1953 date). The steel base has a black hard rubber insert to protect the firing pin during practice. The Bofors gun had a harsh action and the ammunition had to be made accordingly. This 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 1781
