Look at the photo closely. You will notice that when the flat hinges are open, one leaf is higher than the other half, but when the hinge is closed, both leafs are even and the difference has been taken up in the spine. Thus, when the door is opened, the hinges lift the door slightly, but when it is closed, the door is lowered closer to the floor. Neat, huh.
This 3 3/4 inch size hinges were made by the I.G.H. Company of St. Louis, Missouri. They date to the first 20 years of the 1900s. They have the flashed copper treatment of that era, and they have the ball finials as well. Each leaf measures 1 1/2 inches by 3 3/4 inches.
This pair appears to be new-old-stock–un-used. The finish and flashing are in excellent condition. We will add 12 appropriate screws.
