The German sub-machine gun EMP-35 (Erma Maschinenpistole 1935, or French PM Erma Mle 1935) was designed by engineer Heinrich Vollmer and produced at the Erma factory from 1930 to 1938 for export (Spain, Mexico and Yugoslavia). The EMP was tested in the Spanish Civil War. It was produced under license in Spain by the arsenal of A Coruña under the name of WFP Mle 41/44.
