It's Austrian, that's all I know for sure...The red cross is called the Kruckenkreuz with the Austro-Hungarian Double-headed eagle...
I don't think this is military what does it say on the buttons I see hats like this a lot when in antique stores most of them are some sort of civilian organization like the odd fellows not sure what this one is
thanks for your help
emblem on the button : crown and the cross, with latin's word
It looks masonic to me , they use that type of cross I believe .
