Peter Wright anvils are measured in hundred weights, and if you can get a fair one at a good price, jump on it !!
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 pounds2 · 1 · 3 = (112 x 2) + 28 + 3 = 255 pounds2 · 2 · 25 = (112 x 2) + (28 x 2) + 25 = 305#
therefore, your anvil should weigh 175#
