K mark, Thanks

ok K means that this binoculars belonged to a Military officer or Commander of Kaiserliche marine during world war one, in my opinion!

K is the inspection mark for Spandau signifying it's been quality checked for army use.

you are right!
K = Gewehr Prüfungskommission Spandau acceptance marking. This marking is often found on German army world war one period binoculars but not on ones made after this war!
