Rare turning table for the 10×80 Flak spotting binoculars marked clk

Rare turning table for the 10×80 Flak spotting binoculars in excellent, working condition. Nicely maker marked clk indicating production byF.W. Breithaupt & Sohn, Kassel.The base retains its full wartime factory finish. All turning knobs are adjustable. The knob for locking the optics is slightly bent but usable. The mount has been made a smaller size with a small lead or zinc plate which you can take out if need be. One of the crucial components for a fully functional D.F. 10×80 which is virtually always missing. Nice example!
