Japanese small stereo trumpet of the WWII period

The original 10x stereo trumpet is in good collector's condition. The body of the MCT is made of aluminum alloy, covered with black artificial leather. Two periscope tubes (a modified Porro – 2 prism system) are connected by a hinge with the possibility of fixing the position of the tubes using a special latch (clamp) made in the form of a "wing nut" (in 1915, the design was apparently changed). The device is equipped with a wooden handle for ease of use and for the possibility of installing the MCT in a stationary position. The fastening mechanism of the grid allows you to change its position relative to the horizon. The prisms of the lenses are protected in non-working position by special rotating cylindrical shutters. Very rare. Guarantee of authenticity.
