These are polished-brass castings with pressings forming the finger recesses.
Typically used on military or campaign-style chests, they are handsome handles for any chest or large box. Size is the overall width, height and depth of the handle.
The 2 1/2” × 1 1/2” × 5/16” handle requires #3 screws; the other two handles require #5 screws.
