This pair of book ends are really nice and heavy. They are bronze. Each has a number, PMCo 89B. One has a sticker on the bottom, PM A product of the finest American Craftsmanship Philadelphia Mfg. Co. Philadelphia, PA. One has a replacement pad on the bottom. The one with the original felt weighs 4 lbs. The one with the replacement pad weighs 6 lb. My guess is that someone has added weight to the hollow inside. Both are in very good condition. These are useful and lovely.
