This is a very heavy brass pair of stop hinges. These may be what some people call “butler tray hinges.” Each hinge will fold together, but upon opening, will stop on a flat plain or will not bend beyond 180 degrees. This old pair is thick and heavy and can withstand a heavy leaf.
Each hinge is 3 3/8 inches long and 1 3/8 inches wide. Each wing is 1 5/8 inches deep and 1 3/8 inches wide.
Brass screws will be included.
