VINTAGE CLAMSHELL HALF MOON SPOON unknown pattern brand FLATWARE SILVERWARE SILVERPLATE

This is vintage silverplate flatware: 1 small long handled iced drink spoon 6 1/2". The brand is UNKNOWN. There are no backstamp or markings. The handle design is a high-relief clamshell at the handle tip, with half-moons? The markings look like it was hand made. I have no idea if it's sterling or stainless. There's NO heel wear or plate loss, so it's not plated. A magnet doesn't stick to it. It weighs over 1/2 ounce, and less than 1 ounce. So, it's just a cute little spoon, vintage, maybe handmade, maybe not, maybe silver, maybe not... a unique piece all around, tho.
