I’m looking for photos of unidentified 7,92x57 ammunition with markings from years 1919-1922, which may be related to the production of ammunition in Gdańsk by “Gewehrfabrik Danzig”.
Although it could be independent of it and could have produced in artillery workshops? (in my theory).
Some of the ammunition maybe was to be produced for a contract for Poland in 1920.
It is highly probable that such ammunition marking may consist only of a production date in the form of a year or a two-digit tip, without manufacturer code markings.
