SMGM-0319 NSAP årsting göteborg 1934 tinnie (Swedish Nazi Party)

Nonferrous. From what i can find on these badges, there seems to be two makers. Both makers had slightly different dies. This one has a highly detailed castle/fortress with pronounced small pebbling background, very detailed grass area, no maker mark on the back, has a pin base plate and has a more distinct style “1” in the date.  The other version I have seen has more muted features, a maker mark on the back and the pin has no base plate. Then there is a horrible reproduction that has a coffin back pin and major casting flaws. If you know more about this rare badge please email me so that i can update the listing.
