7.92x57mm ball ammunition box '1943 dou'

Original card ammunition box which would have held fifteen 7.92x57mm S.m.E. ball rounds. Still complete with the factory label, this example is dated 1943 with the maker code 'dou' to indicate production by Waffenwerke Brünn A.G., Werk Povaszka Bystrica. A nice period accessory which is retained in very good condition!
