Well in my opinion it is a good tomback example,the hinge,catch are the correct type for a Schwerin badge and the pin seems to be showing the expected curve.The detail of those little "dots" running around the bottom edge of the badges reverse is also a good sign of an original as is the slightly out of line B in BOCK..I do agree the Adler looks a bit weak on detail,but that could be down to a slightly thicker layer of gold,the eagles and wreath on originals are not greatly detailed in comparison the ship anyway!! Just my opinion but I think it's a good one.
This fellow is a scammer. He posted a similar post on the helmet forum trolling for buyers. He did not own the helmet he showed. Read the following thread:
LIFE'S LOSERS NEVER LEARN FROM THE ERROR OF THEIR WAYS.
Why has this person not been banned yet? He has all sorts of threads started asking "real? and What's it worth?" . I would suggest that no one give this person any further information, as he likely does not own the items shown....
