The Bren Gun Spare Parts Wallet is a holdall with four internal pockets for organising and carrying small, easily lost, spare parts for the Bren Gun. It also holds equipment for cleaning the gun in the field.
During World War II, the wallet was typically carried by the No. 1. gunner (the man on the trigger), for which it features an adjustable shoulder strap. When not carried by by the No. 1 gunner, the wallet could be carried in the large pocket on the Bren Gun spare barrel bag (not on display), which was carried by the No. 2 gunner (who spotted targets for No. 1, replaced empty magazines, and changed barrels).
