Looks like russians Especially, you're. Great ushanka. Mustache is too typical for "starschina". But the overcoats have to be light grey (unpainted wool) or green (lend lease material). Mostly green in the end of the war. Dark grey overcoats mostly typical for officers, but for starschina as well . You used a postwar russian overcoats. The style is the same, only different color. We used them too, even now some of us use them. On the second picture you can see the difference between color. There is a woman-medic on a postwar overcoat and upper is a infantryman on a right overcoat.
The difference in color is small but it is.
