Hi, according to the Alpenkorps history, the Austrians gave them 20 000 of these badges. I assume that was the initial lot, and maybe guys added and changed and found others as they went along? I would guess that there must be variations and that they were all roughly the same size and form, but not all exact matches with badges from another maker? Here is one I cannot date, it is well travelled, has crossed the atlantic twice ;-) Traces of the original silver on the back... I am assuming it is WW1 Austrian issue, it was found in Bavaria, so maybe used by te Alpenkorps? Or maybe civilian, although I assume civilian associations have some initials on them like the D OE V ?
