7.92x57mm Platzpatronen boxes set '1944/45'

A nice set of four original paper ammo boxes which would have once held the wooden-tipped 7.92x57mm Platzpatronen drill rounds, as used used with the K98k, MG34/42 etc. 
 
The boxes remain in good, used condition and come complete with the original factory labels. All four are dated 1944 from the factory, however, one box also displays a faint '1945' overstamp on the label as shown!
