Vintage Double Action Spring Hinge

Brass hinge measuring right at 5 inches in length and 3 1/2 inches, when in the position shown in the photograph. It weighs 2 pounds. There are paint splatters and age related wear to the surface. The photograph shows 2 hinges to see the front and back view, but the price is for one hinge. I need your zip code to calculate the postage.
