Continuing with a U-boat theme here is a 3.7cm Flak gunsight which I am told was used on U-boats but I have never come across any pictures of it actually in use.
It has 4x selections for airspeed with different aiming elliptical graticules, some very fancy readout adjusters, selectable 2x or 5x magnification and a selectable neutral density filter.
Made by Carl Zeiss Jena (blc) and designed for the 3.7cm Flak SK C/36 which also appears to be very rare. As a D.O.K. Instrument it was also submersible so not required to be removed from the gun for diving.
Any thoughts out there?
