Bronze Infantry Assault Badge. Maker MK in Triangle.

Zinc based and in a very good, probably unworn condition with practically all of the bronze wash still present.
Marked the the reverse, under the hinge with, what appears to be a stylised, „MK“ in Triangle. An unknown maker but possibly standing for Metalle and Kunstoffe from Gablonz. See GCA database.
Very difficult to find in bronze and in such condition.
