This flat surface-mount cabinet hinge pair has a nickel-like finish. They were made by the National Mfg. Co. Their flag logo is stamped on the back of each hinge. They date from about the 1930s to the 1950s.
Each hinge measures 1 5/8 inches vertically and 2 3/4 inches across both wings. Each wing is 1 1/4 inches deep (or wide).
This style is fairly uncommon. We will provide screws.
