I'm afraid to ask for opinions on this WWI EK1, but I feel I have to know.
The badge is perfectly square, but 43 mm x 43 mm. thickness of the iron plate is about 1mm. the who medals weights 14.1 gm. There is no curveture to the medal. Definietly 2 piece construction and the main plate is magnetic. No Marking as far as I can see.
