Would early war or pre-war wehrmacht heer feldwebels (or more specifically, oberfeldwebels) ever have worn riding pants as part of combat field dress?
NCO uniforms were kind of in a weird place in that as far as I can tell. They had infantry straight trousers for field dress, but were authorized to wear the officers riding pants for semi-formal events using nicer field uniforms (instead of full dress uniforms) such as parades and such. I've also seen some guide pictures from ospreys and such through google searches that APPEAR to show NCOs with riding pants, but the labels are gone, so I'm not 100% sure what's being displayed. For example, the fellow on the right
appears to be an NCO, but I'm not sure? His shoulder patches are unfortunately not shown and it's hard to see the shoulder straps, but they look like feldwebel boards?:
EDIT: Actually, maybe those look like officer's shoulder boards to me. Not sure.
Also, I know that in the wehrmacht, many men, not just officers, would personalize their uniforms in small non-regulation ways, such as removing the wire stiffener from the hat brim, wearing tall parade jackboots instead of the shorter regulation field boots, sewing on older, more colourful (and more visible) rank insignia and markers, and so forth.
I need to do some surgery to create a particular figure and the legs I want to use have the riding pants. It's okay if it's unusual, because it's for a rather special unit, all I really need to know is if the practice wasn't totally impossible or out of the question for some reason.
