I’ll be happy if you can help me ID some of the items. Thank you very much!
The two first items are remains of .303 British rounds, fired in a Bren machine gun. The way you can tell the latter is from the shape of the firing pin and the dent made by the gun’s ejector.
Although the first case is British .303" it is of Canadian manufacture - Dominion Arsenal, Quebec
Images 4, 5 & 6 are of a No. 117 British artillery fuze
The second .303 round was made by Radway Green in 1941 (UK). They used a single broad arrow in 1940 and 1941 to try and hide the fact that a new ammunition factory was operational. They replaced the broad arrow with the initials RG in 1942.
The last 4 are some kind of folding/pocket knife.
