This brass-toned cabinet hinge was made by the National Lock Company of Rockford, Illinois. Their stamp is on the back of the hinge. The hinge is steel. We think this hinge dates to around the 1960s.
The hinge measures 1 1/2 inches vertically and 1 1/2 inches across. Each wing measures 5/8 inches across.
We have lightly cleaned this hinge. Screws will be included.
