A very nice sterling cowboy belt buckle with overlay (gold) and tooling on the silver.  A horse head is prominent on the front of the buckle but the tooling is really great!  It is from “Robt. W. Boyd, Reno, NV Sterling Overlay”.  It measures 2″ x 3 1/4″ and should fit a belt 1.5″ to 1 3/4″.  A nice vintage belt buckle.
