Haenel MP28/II Machine-Pistol
This weapon is an MP28/II machine-pistol designed by Hugo Schmeisser, based heavily on the WW1 era MP18/I. The MP28 was provided with either a 20 round box magazine or (later) a 30 round magazine. This one I picked up didn’t have a magazine with it but luckily the magazine for the Sten or Lanchester MP’s were almost identical so I’ll put a Sten mag into it until I can find an original MP28 magazine.
The MP28 was used widely between the wars and by the Waffen-SS and Polizei during WW2.
