After a few hours of searching the internet and various reference books, I am still unable to get even the slightest clue as to what this is.
To me, it seems very close to the Polish eagle crest, but, without the crown. However, the crossed swords seem to be U.S. Cavalry type.
Perhaps someone can assist me in shedding some light upon this enigma.
It measures 44mm X 37mm.
Many thanks in advance.
