I have seen this button before but can't remember where..any thoughts as to what country this from?? Thanks MIke

It is Hungarian- The crown of St. Stephen

thanks..I was not positive on it's origin. Not sure why it is so hard to ID older military buttons--google and bing have very little on them. anyone have any good reference sites for buttons or book suggestions?? Mike
