Bamberg Liquid Compass

<< >>
Carl Bamberg (1847-1892) served an apprenticeship with Carl Zeiss at Jena and studied at the Universities of Jena and Berlin before establishing a "Werkstätten für Präzisions-Mechanik und Optik" in Friedenau, a suburb of Berlin, in 1871. After Bamberg's death, the firm was managed by his widow, and then by his son. Bamberg merged with the Centralwerkstatte Dessau in 1921, forming a new company known as Askania Werke.
The inscription on this compass reads "CARL BAMBERG No 34717 BERLIN-FRIEDENAU GES. GESOH." and "Carl Bamberg Berlin-Friedenau 1915 Kaiserl Marine."

I have a compass stamped carl bamberg 00407 m.1860 Berlin friedenau. Would this be a ships compass or an air craft .
I have a similar looking compass stamped: CARL BAMBERG NO34476 BERLIN - FRIEDENAU I was given it many years ago, and was told that it came from a WW1 German bomber.. There is nothing attached on the top of the lens.. It is fully gimbaled, and still functional.
