You can see it is hand worked with the right tools.. Has neillo on it,,the gold flash plating to cartouche,,even the right hallmark..
Unorthodox yes, but there was a war going on,,sh*t happens..
Could have been 50, 75, 100 made and maybe only a few survived.. IF as the usual DAK of its kind there would be no question...
A nice to see something different, rare one ,,you have another to hunt for,,be happy!
