A half-mortise hinge is one where the plain half of the hinge is embedded into the jam or frame (mortised), and the fancy butterfly half is fastened to the front of the door. This allows the spine hinge to protrude away from the door. This pair comes out of the first two decades of the 20th Century. They were made by The Stanley Works of New Britain, Conn.
The popular finish in hardware from 1900 to 1920 was flashed copper. The steel base was coated with copper and then flashed with a black lacquer. Over the years this finish wore off or did not stand the elements real well. This pair of hinges still have most of their copper coating and are somewhat rough, but they are still handsome. The butterfly pattern is quite unusual and is a challenge to locate.
The mortised wing measures 3 1/2 inches by 1 1/2 inches. The butterfly wing is 3 1/2 inches by 2 1/2 inches. From ball finial tip to ball finial tip is 4 3/4 inches.
We have cleaned and oiled the pair. Screws will be included.
