The Ros Figures Austrian range is limited to just three figures: a Grenadier, a Musketeer and a Jager.

He wears gaiters, so I am guessing that he represents a German infantryman, as opposed to his Hungarian cousin. Well, that's how I have painted him!
I have seen pictures of the Austrian Grenadier, but have never seen the Jager and I would welcome any information about that figure. Here is the Musketeer:
