I second that! At the moment busy with reading the two Ospreys about the Russian Civil war. Those winter chaps indeed would work well for RCW. And those summer chaps too, with some head swaps. Naval infantry, Checka troops in leather coats, Freikorps troops, Polish, Japanese, Western intervention troops, White troops in a mixture of western supplied and old Tsarist uniforms and equipment, etc. The ww1 cavalry sets too work well for this period.
