Oh, and just for future refrence, the log on it, the eagle over an anchor, is the trademark of Fisher & Norris, there were many variations over the years of the logo, but there can be fisher & norris anvils without the logo, usualy labled Fisher along the foot.
Like vulcan anvils, Fisher anvils are a tool steel face welded to a cast iron body, hence why it wont ring, even if it has good rebound. If you get heavy chips on the edge of the face during use, it's actulaly safer to put a very heavy chamfer on the edge, or round it down completely, to grind the chip out than it is to keep using the anvil and avoiding the chip, because it will just get larger. I've got a 75lb vulcan which i've ground probably half a lb out of on 2 edges to round it down (not quite finished reshiaping it yet but have the rough done with an angle grinder) Using the flat between it is still fine now that the damage is being prevented from being spread.
EDIT: From the logo in use, and the shape of the anvil, looks to be a rather old one, probably late 1800, Fisher actually made anvils up till the 1970s, however for the last 50 years or so of the company most of their anvils were made for the government, Most ship anvils used by the navy were fisher anvils
