Deactivated Super Rare WWII Nazi MP3008

We have managed to source several exceptionally rare genuine Nazi manufactured MP3008 machine gun and a handful of spare parts. All have been recovered from a factory/warehouse that was heavily bombed by the US Airforce in 1944. After the war the area was cleared and the contents buried in a bomb crater. In the 1960s the German Bunderswehr (Federal Defense) took control of the area which was used as a military installation until 2006, whereupon contractors clearing the site discovered these parts. We have a letter of provenance with pictorial documentation of the discovery.
