I was having trouble finding information about my regiment as well. The only thing I knew about them was what nation they were from and what side they fought for. I ended up finding a German Wikipedia article on them, but if Google translate didn't exist, well...
Its also very hard to find pictures of our regiment in real life since it wasn't really known, only a few pictures in WW1 and in the 1790s, but nothing on their uniforms during the 1870s, which is annoying seeing all the other regiments with all these pictures depicting their regiment in firefights and shit, lol.
