A superb and very scarce boxed example of the Wehrmacht issue 12x60 rangefinder binoculars. The optic itself is nicely marked to the top data plate with the'blc' maker code, signifying production by Carl Zeiss in Jena.  Retains the majority of ordnance tan finish. The rubber headrest pads and the Bakelite ocular cover are also still present. The optics are crystal clear. The original storage/transit box remains in similarly good, original condition and is also'blc' marked for Zeiss with the vast majority of the original tan finish remaining intact to both the exterior and interior. The original paper contents label, and all of the internal wooden fittings to hold the binoculars securely, are also retained and have not been stripped out. All in all, a truly stunning example of their type which would make the perfect addition to any optics related collection! The rangefinder Kommandogerät 36 (COMMANDER 36) was constantly developed and it worked on a geometric-linear basis. The 4 m rangefinder (short: Em 4mR (H)) was placed on the calculator. The firing values were transmitted electrically via a 108 core transmission cable to a distribution box in the middle of the battery and further to the guns of the guns. In case of failure of the lamp dispenser system, a telephone transmission to the guns was possible. Despite this very well working device, however, man-made errors were unavoidable in 13-man operation, which required the device. To avoid these sources of error as much as possible since 1937, the company Zeift has been busy developing a device that can help humans with mechanical components such as more than 20 electric motors, switch boxes, cam bodies, and differentials. Friction gear and regulator should replace. 1940 came first a command device to the troop, under the name KAPPA DEVICE, the three-man operation on the stereo-effect rangefinder 4mE (R) 40 required two man on the computing device coupled with it, and a man at the collector with control box and machine set for the device and transmission current. The name Kappa device had the new device according to the Greek letter Kappa, who in the Flakschießlehre (anti aircraft gun target shooting) designated the course angle which this device could overlook. The later name of this device was Kdo. Ger. 40, improves to Kdo.-Ger. 40B and 40C.
