I was wondering if you could do a skin replacing the second austrian line:
The "Böhmisch-Mährische Legion 'Erzherzog Karl'" was an austrian military unit, and little is known about how it really looked like. I found two pictures - both show the same uniform, so I guess thats the closest I will get.
If you find the time to make it, you would make me very happy.
And if you are really bored, there is a rifleman in the background of the first picture, he's wearing the uniform of the rifle company.
