Hi.
I´m sorry to say but this is no real Officer. It is the Stage-Play Actor
Hermann Böttcher around 1902-1903 in the play
„Im bunten Rock” (you can read the name and title in the left corner), .based on a story from the famous german Ex-Officer
Wolf Ernst Hugo Emil von Baudissin, in Germany better known under his Alias-Name "Freihherr von Schlicht", under which he wrote mostly humorous stories and novels about the military.
It is possible that an HR 8 uniform was used, but it may also be that the uniform (at least the shoulderstraps) were a fantasy product.
