"Sterling Overlay" means that a heavy layer of sterling silver was bonded (not plated) to the surfaces.. which results in an almost identical appearance to solid sterling silver and much better durability than electroplated buckles.
The 3 piece buckle set also has a black leather belt attached to it that measures 42" from tip to tip and is 3/4" wide. The leather belt does show moderate signs of use and some wear. The main buckle measures 2 1/4" x 2" and has an opening to take belts up to 1 wide. The keeper has a 3/4" opening and the end piece has a 5/8" opening. We have HUNDREDS of additional classic vintage American cowboy, western, rodeo, trophy and ranger style belt buckles currently listed for sale.
