One Vintage Atchison, Topeka & Santa Fe railroad spike hammer weighing in at 9lb, 11oz, (maybe an ounce or two less once you remove that old piece of wood handle from the eye) and measuring 14-7/8" long. The big face is 1-5/8" in diameter and the little face is 1-1/4" in diameter. See pictures for all the number and letter markings. Thanks for looking!
