MG34 Patronenkasten 36 ammo box 'ada 1941 WaA'

A very nice original 'Patronenkasten 36' model ammo box for the MG34. This type was designed to be used in conjunction with the Zwillingssockel twin MG34 anti-aircraft setup. 
 
This example retains much of the original early green paint, over red oxide primer. It is also nicely maker marked and dated 'ada 1941', along with a Waffenamt proof mark.
