Obverse view, from top to bottom and from left to right (same order applies to the reverse view) :
E 01- The Best Border Guard, S/N 927 (visible at 6 o'clock on the reverse of the Badge). Both the Badge and the screwplate were manufactured in the former USSR, by the Moscow Artists Cooperative (original screwplate marked accordingly), during the 1930s-1940s. Good overall condition.
E 05- The Best Border Guard, numbered (at 6 o'clock on the reverse of the Badge) with the Cyrillic letter "V" (which looks like a "B") followed by number 491 (B-491).
Made in former USSR, by Podeba Factory in Moscow, circa 1960s-1970s.
Original screwplate. Good overall condition.
E 06- The Best Border Guard.
E 04- The Best Border Guard.
Have no clue where these two types were manufactured, or the period during which they were used.
