Greetings Generalstab.
PLEASE would greatly appreciate any info regarding the three posted pictures. My research has led me to believe that the solo-pictured Gustav Noll (my great-great uncle) was a Sergeant Major, photo taken circa 1914. Also I believe there is something to be learned of his sword.
The second picture (smaller group in entirely different uniforms)
has proven considerably more difficult to date and identify, as it appears the uniforms of this style did span a greater number of years. My best guess places me between 1890 and WWI feldgrau, I hope for more specific information, the earlier date would place a family member for whom we have no photographs. After converting color pics of similar uniforms to B&W, I wonder if these are the black collar dunkelblau of artillery, but I believe these men would be limited to Bavaria for lack of bombs on shoulder straps. Otherwise I suspect infantry. Not exactly sure of the significance of the Brandenburg cuffs, if any. The belt buckle in both pics (just the raised crown without a circular border/phrase), is one of which I have not been able to find any information or other pictures online.
The final pic is of my great grandfather Julius Noll, who I believe was a medic. There appear to be markings on his collar, would appreciate knowing what these mean.
Thank you for ANY information and clarification.
