9mm Steyr or Bergman?

the headstamps on these 2 pistol rounds are H 1915 and V1/19/16/SB I know who made them, and both have brass cases and steel jacket bullets but I would like to know do I have Bergman, Steyrs or one of each , thanks Randy

Probably Both Steyr M1911 9x23 cartridges…H Hirtenberger PatronenFabrik,
VI 19 SB 16 Sellier & Bellot, June 1916. For Austro-Hungarian Empire

We can take out the word “probably” from Doc Av’s answer, as he is perfectly correct. In the case of the cartridge made by Sellier & Bellot, it was made in what was to become Czechoslovakia, but just as Doc Av did, it can also be referred to as an Austro-Hungarian cartridge, historically perhaps more correctly, since Czechoslovakia was part of the Austro-Hungarian Empire at that time.
