The M2 Browning .50 Cal Heavy Machine Gun or Machinen Gewehr is you're German :D It was produced by Browning Arms and developed by John Moses Browning, also the inventor of the BAR, Auto-5 Shotgun and M1911 Pistol. I really hope that I didn't copy anyones design on this one.
About this creation
Here we have our good friend Mr. Indiana Jones showing the comparison between gun and fig. I think I got it pretty close to scale with a minifig.
