Early MG34 anti-aircraft spider sight 'BSW WaA4'
An excellent original AA spider sight for the MG34. This particular example is very well marked, and hence is certainly of early manufacture (pre-1940). The markings include the 'BSW' logo & 'WaA4' stamped on the outer ring, along with further 'WaA4' stamps to the base - all indicating production by Gustloff-Werke, Waffenwerke Suhl.
One of these parts would have been carried by every MG gunner, and was held within the belt-mounted tool pouch. Definitely a must-have accessory for any MG34!
