Here is a nice photo of some of the officers and N C O men posed for the Kaiser Parade
of A K I at Konigsberg 1910 .The photo is by the famous Oscar Tellgmann
I think the men are I R 45 / III Batl
on a second look, the NCO on the extreme right of the standing rank is also a Feldwebel. I missed to double cuff rings at first inspection. So all four company sergeant majors are in the group albeit unnamed.
