This pair of Hoosier-style hinges was made by the National Lock Company of Rockford, Illinois. They have a 3/8-inch off set.
The narrow wing, that mounts on the frame of the cabinet, measures 1/2 inch wide by 2 inches vertically. The wing, that screws to the door, measures one inch wide and 2 inches vertically. They can be used on either a left-hand door or right-hand door.
These hinges are steel and very clean. They are loose and ready to use.
