Auxiliary Cruiser War Badge. Sterling.

Real silver based and in a very good, slightly worn condition with most of the gilt plate still present.
Marked on the reverse with „Sterling“ for Sterling silver. These type of badges are well documented as being made by a Japanese jeweller for crews of German ships visiting Japan.
This particular badge belonged to an Ober Feuerwerksmaat from the auxiliary cruiser Thor. Also to the badge are several, made in Japan, cloth Kriegsmarine trade badges from the same man.
Very difficult to find, one of the few originals.
