USA 1980 Olympic belt buckle from Bergamot Brass Works of Delavan Wisconsin. This appears to have been a souvenir or money-raiser for the US Olympic teams for the 1980 Moscow games. These are the games which the US boycotted.
It measures about 2 inches by 2 5/8 inches, with a 1 3/4 inch swinging bale.
Very good condition.
