They are " M "marked on the rear of the right case, and with the wartime military-ordnance code of " BEH " on the rear of the left case of the binoculars, as well as serialized. They are also marked K. F " over " O , denoting internally treated with Low-temperature lubricant. Original neck strap also present. Original case is Waffenampt-marked WaA14 and also 1942 dated.
EXCELLENT, clear optics with good collimation and good adjustment, given their age. Independently-adjustable black BAKELIT eyepieces are in very good condition, with no cracks or chips. I have started to sell off some of my WWII German optics (new expected addition to the family); watch my listings for more interesting items.
