Herman Kohlbusch Balance Scale No. 17 with Troy Ounce Weights, ca. Late 19th Century

An excellent surviving example of a late 19th-century analytical balance scale by Herman Kohlbusch, manufacturer of high-precision scientific instruments in New York. This model is marked as Balance No. 17 and retains its original instruction label inside the drawer, showing the firm’s address at 59 Nassau St., New York.

The scale is housed in a fine hardwood and glass case with two pans and a fitted set of troy ounce brass weights, indicating its use in gold, bullion, or assay work. Troy weights (rather than avoirdupois) were essential in 19th-century precious metal transactions. The brass weight set includes denominations clearly marked 10 oz troy and 5 oz troy, among others.
