This antique door hardware assembly was manufactured by the Yale and Towne Manufacturing Company. The set consists of a cast bronze or heavy brass escutcheon plate, a cylinder lock, and a spherical doorknob. The escutcheon features a transitional architectural design with segmented arched terminals and a textured, stippled field. A raised Yale logo is visible on the cylinder lock face. The hardware is mounted to a rectangular wooden board with a distressed green painted finish and a Yale stamp at the top. The assembly is equipped with a wire loop for wall hanging, suggesting it was used as a showroom sample or display piece.
