This pair looks as if they may have come off of a walk-in cooler. Their pattern remind us of the Art Deco era (1920-1940). They are heavy cast aluminum and have a 5/8-inch off set.
Each back plate, that mounts on the frame, measures 1 1/4 inches wide and 3 inches vertically. The larger wing, that screws into the door, measures 4 inches long and 1 7/8 inches vertically.
We have only dusted this pair. They are loose and in good condition. One hinge has a nick on the front of the facing wing. Screws will be included.
