RUKA 6x30 Dienstglas 'dym' + case 1937

A notably scarce example of 6x30 Dienstglas binoculars which are maker coded 'dym' to signify for production by Runge u. Kaulfuss, Rathenow (RUKA Rathenow). 
 
This pair remains in nice, field used condition - and totally uncleaned, as found - yet still retain the vast majority of the original black paint and textured grip coating to the barrels. 
 
The optics produce a fantastic, clear image and complete with the H/6400 Strichplatte rangefinding reticule in the right-hand side. 
 
Also coming with an original early period 1937 dated leather storage case. 
 
Overall, a very nice and honest Dienstglas from one of the more uncommonly observed manufacturers; as well as one who were mainly associated with supplying their optical equipment direct to both Polizei & Waffen-SS personnel!
