I've been trying to find good reference pics myself. The garment is called a "gymnastiorka", or something else. It depend how you transcribe the cyrillic script. Check under the Red Army section, Uniforms, at www.aboutWW2militaria.com The pre-war M35 type used collar tabs, while the wartime M43 switched to shoulder-boardfs and simplified the collar. Apparently there were a lot of boots and buttons supplied under lend-lease from the USA.
