In the chatroom, last night, you expressed "reluctance" to pound on an "antique". These anvils, mostly manufactured in the 19th century, were made with the express purpose of banging hot metal atop them with a hammer. They accomplish, with few exceptions, their appointed task. If used properly(no pounding on it when the metal is cold", these anvils will last a thousand years, if used in the right manner. Your respect for these tools is a good thing; you will certainly not abuse your 150 pound antique "treasure"!
