Erma EMP: Heinrich Vollmer's Interwar Submachine Gun
This video from Forgotten Weapons explores the distinct Erma EMP submachine gun, designed by Heinrich Vollmer in the 1920s and marketed by Erma starting in 1932. The video highlights its international sales success, including its use by German police and Republican forces in the Spanish Civil War. A key focus is comparing the original German Erma-produced models with the Spanish MP41/44 copy manufactured in La Coruña. The description also notes that many EMPs were surrendered to French forces during the Battle of France.
