US captured D.F. 10x80 Flakfernrohr binoculars 'beh'

A wonderful, US veteran captured/souvenired example of the D.F. 10x80 Flak binoculars (Flakfernrohr) - complete with the original rubber headrest pad, detachable front sunshades and mounting rail etc. 
 
Finished in the original ordnance tan paint, which remains intact to a very high degree, this particular pair are clearly maker coded 'beh' - indicating manufacture by Ersnst Leitz GmbH, Wetzlar. One of the more rarely seen maker codes for the 10x80 in comparison to other manufacturers.
 
Optically, this set will definitely require some attention on the left-hand side if intended for any sort of use, due to 3x internal screws being loose inside the main housing. These loose screws have caused scratches to the internal surfaces resulting in a hazy/unclear view on this side. However, the right side still remains functional, clear and contains the crosshair aiming reticule. Both focus knobs still function as they should, as well as the sun filters and ocular width adjusters.
 
Incredibly, the binocular itself still comes with the crate in which it was originally shipped from Europe over to the USA. This box was repurposed from a captured German ammunition box, that was originally produced in 1939 - but clearly one that saw continued use until at least the end April 1944 when it was labelled as being filled with Platzpatronen 33 (wood-tipped 7.92x57mm dummy rounds).
 
The box is complete with both the USGI sender (Cpl. W. M. Dwyer) and family recipient details hand applied to the front of the box, as shown. 
 
A truly incredible piece of WWII history that remains a true time capsule set, exactly as it was captured and subsequently returned to the USA as a trophy of war, with definite research potential! A unique display piece!
