I don't understand the challenge for a member to prove something is fake! The burden of proof should be to the presenter of the piece to show/prove its authentic when questioned.
Why is the maker marking so worn to the point that some letters are almost obliterated/unrecognizable. It is because they are cast in,,and done poorly..
And it is correct that the piece should not have the marks cast in,,but stamped in.
The 'Halbmond und Krone' markings do not look like Gahrs. Nor does the crown resemble anything even close to other German crowns used by other makers.. . For whatever the reason the markings do not seem to be correct..
