Soviet budjunovka 1930s. Widely used during the Finnish Winter War and a couple of years into WW2. This example is in very good condition, you can clearly see from the gray wool when you fold it down that it has been folded for a long time. Marked inside the cap with an ink stamp "Cyrillic letters, star, 57 and the year 1937" in front a green star for the border troops. The red enamel star has never been mounted. Very odd and rare object (€310)
