Re. Weapon Request: The pistol is a Makarov. The submachinegun is a Polish PM-63 RAK. http://www.military-today.com/firearms/pm63_rak_images.htm
Did a little research: The PM-63 wasn't used by the NVA but by the 9. Volkspolizei-Kompanie. It was a secret anti-terrorism unit of the MdI (ministry of home affairs) of the GDR.
