Nice cross, Greg, congrats!
In my opinion this is not Austrian mount. It is quite common style how prussian veterans folded their ribbons in 1870 - 1914 era. I watched this piece on eBay, so I know there isn´t typical Austrian device on the reverse (hook and eye), ribbon is folded and sewn together prussian style and topped with button (sorry, I took reference photos ).
Nothing changes on the fact, that this is nice Prinzen.
