You stole that anvil /forums/images/graemlins/smirk.gif
Hay Budden is an old line US anvil maker. Here's some background:
second United States manufacturer of anvils was Hay-Budden Manufacturing Co. (James Hay and Frederick C. Budden), Brooklyn, New York. They supposedly began operation in 1890 and went out of business in the era of 1920 to 1925. In 1905, Hay-Budden claimed that there were over 100,000 of their anvils in use. Hay-Budden advertising says: `Every Hay-Budden Anvil is made of the best American Wrought iron and faced with the best Crucible Cast Steel. Every genuine Hay-Budden Anvil is made by the latest improved methods. Top and bottom are each one solid piece and welded at the waist. The steel faces to these anvils are all put on in one solid piece: not two or more pieces, as is customary with most anvils ... we have produced a steel for the faces of our anvils which will take a harder temper and be less liable to chip than any on the market ... and the blacksmith who wants a strictly first-class anvil can make no mistake in purchasing a Hay-Budden."
Hay-Budden manufactured a number of different pattern anvils, making the farrier's anvil with and without the clip horn. They also made an Plowmaker's Anvil, a double Horn Anvil, a Hornless Anvil, a Sawmaker's Anvil, and Cooper's Steel faced Beck Irons.

Anvils-6: Weight of Anvils
Anvils are marked in a variety of methods but most English anvils were marked using the hundredweight system. However, some English anvils were marked in stones and anvils made in other places (including many Swedish anvils) are often marked in pounds. A few are marked in kilograms and some cast anvils are marked in pounds rounded to the nearest 10 pounds (250# = 25). Cast markings are easy to identify as they are usualy raised figures rather than stamped into the anvil. Then there are the many unmarked anvils. . . If you are not sure and you really need to know then weigh it.
Hundreds Weight (hundredweight) System:
Typically the hundreds weight markings are seperated by dots but not always. These figures were stamped into the finished anvil and are often not very deep. The first figure to the left is hundred weights which equal 112 pounds. The next figure is quarter hundred weights which equal 28 pounds and the last number is whole pounds. The three are added together for the total weight. Examples:
1 · 0 · 16 = 112 + 0 + 16 = 128 pounds
2 · 1 · 3 = (112 x 2) + 28 + 3 = 255 pounds
2 · 2 · 25 = (112 x 2) + (28 x 2) + 25 = 305#

Based on your "224" marking, the weight would be
(2 * 112) + (2 * 28) + 4 = 284 lbs.
