- Description
- These cylindrical brass weights are part of a set of standards prepared by the United States government. They weigh one pound Troy, one pound, two pounds, three pounds, four pounds, five pounds, ten pounds, and twenty pounds. A knob at the top of each weight makes it easier to lift. The set also includes a weight lifter.
- All the knobs are stamped with an image of an American eagle. Those in this set, except for the Troy weight, are marked: 69. A mark on the knob for the Troy weight reads: 9.
- The weights fit into cavities in a velvet-lined wooden case. The amount of each weight is indicated on a paper tag attached to the base of the corresponding cavity.
- The United States government began distributing weights to the states in about 1845. When the weights were transferred to the Smithsonian from the Bureau of Standards in 1929, correspondence in the files suggests that they were of the type distributed before the Civil War.
