WW2 German Kriegsmarine Coastal Artillery badge by the much appreciated, amongst collectors, manufacturer Schwerin Berlin. Nava badges from Schwerin are reknowned for their high level of detailing, the way that they maintain their gilding / wash after many years and their robust hinge and pin set up (you dont find many with a broken / repaired reverse).
Note -> As always the problem with being a much appreciated antique badge is that they are also the first to be copied and reproduced. From the images shown below there is more than enough detail to make a comparison for authentication purposes.
WW2 Kriegsmarine (German Navy) minesweeper badge by the “high quality” manufacturer Fec. Otto Placzek Berlin Ausf. Schwerin Berlin.
Note: Due to the Schwerin marked badges commanding a slightly higher price / being more “desirable” than other Kriegsmarine Minesweeper badges this is one that is heavily copied / reproduced. Compare as many details as possible to an in hand version before moving forward with any purchase.
