M43 Officers Breeches

[Slobo]

Been searching -- not very sucessfully -- for detailed information on field and company officer breeches so apologize if these questions seem really basic:

-- Did 1943+ blue wool service/dress breeches always carry the same color piping as the tunic and shoulder boards -- Most specifically, royal blue for NKVD, green for NKVD frontier troops, blue for cavalry (and which shade of blue is correct for cavalry?)?

-- Were khaki field breeches commonly worn with service dress -- e.g., with service/dress shoulderboards and sans Sam Browne belt?

-- Were khaki field breeches commonly made of wool/gabaerdine (e.g., like M43 tunics and caps) and not just cotton twill?

Thanks for any info the boarders can provide.
