This tray handle pair are made of heavy cast brass and highly decorated in the Victorian style. These may be that old. Each handle is designed so that when mounted to the surface, the handle has a tilt so that the object or tray can be lifted. The original bolts are very short.
The smooth brass back plates (or mounting plates) measure 2 inches long and 1/2 inch wide. The ring-like handles measure 2 3/4 inches across and 1 3/4 inches deep. The bolts are only 1/2 inch long which must include the nut.
