Button for officer or NCO tunic, 21 mm, ORIGINAL Soviet manufacture, late 1960s - mid 1970s.
Unlike the shiny, one-piece buttons made in the 80s, this one is a close match to the WW2 buttons. It has the same double-piece construction with painted black underside. The brass plated top is almost indistinguishable from solid brass used on WW2 and 1950s buttons.
In excellent condition. Price per single piece.
