Ww2 german original Don cossack volunteers drillich tunic uniform

This is an Original WW2 German Don Cossack volunteer drillich work/combat uniform. This piece has been sitting in my collection for years and the person I got it from was a US major when the wall fell and traveled all around the former iron curtain finding militaria. Please feel free to ask any questions I also have many more ww1 and Ww2 items (us, Japanese, German).
