We would note that the main buckle and 2 keepers are definitely a matching set. The end piece is not exactly matching to the others but still looks great when the entire set is together on a belt. The main buckle was monogram engraved with the cursive letter "M" and measures 1 1/2" x 1 1/2". It has an opening to take belts up to 3/4 wide.
The keepers and end piece have openings of 5/8 wide. The entire set weighs about 1.5 ounces. We currently have many HUNDREDS of genuine, spectacular, & rare sterling silver old western American cowboy, rodeo & trophy belt buckles listed for sale.
