Optical Device H.F.A. II (Höhenfehler-Absteller II) Carl Zeiss Jena, Kriegsmarine, circa 1938

historicacollectibles.com/en/binoculars-and-telescopes/op...

Optical device produced by Carl Zeiss Jena for the Kriegsmarine around 1938, probably useful for correcting the height error in rangefinder measurement, in fact H.F.A (in German acronym for Höhenfehler-Absteller) stands for "Fixed Height Error".
The instrument bears the Carl Zeiss logo on the left with the serial number 21XXXX, while on the right the Kriegsmarine Eagle with H.F.A. next to it, and four-digit military assignment number.
We contacted Carl Zeiss for further information, but it was not possible to obtain it as there are no documents or photos relating to this specific instrument in their archives.
The instrument is complete with its metal box and accessories for its operation.
