Deactivated Old Spec MP34 9mm Sub Machine Gun in very good deactivated condition. The MP34 was introduced in 1930 and went into service with the Austrian Army and police. It was later used by the Waffen SS and they were also exported to many South American countries. They were extremely well made, high quality weapons that are pretty much indestructible. Many were still in use well into the 1970s. All deactivated weapons sold by D and B Militaria are deactivated in the United Kingdom and hold London or Birmingham proof marks and a certificate stating that the weapon has been deactivated correctly and is legal within the U.K.
