Brown wood cased No. 5a assay scale by H Kohlsbusch, New-York. Weights from 1-5 plus small strips. Case 1.25 x 6 x 2.75 inches, inscribed "N C Morris'02" on bottom. C. Herman Kohlbusch Sr imigrated from Saxony, Germany in 1851 at age 29 and opened the Herman Kohlbusch Balance Company in New York in 1859 after apprenticing at Becker & Sons in New Rochelle. In the 1884-85 New York Business Directory Kohlsbusch is listed as a balance manufacturer. Kohlbusch offers 2 models of assay balances (pocket and portable) in an 1888 American Balance Company catalog. His pocket scale is featured in many scientific supply catalogs from 1888 to as late as 1943 and is marketed for assayers, jewelers (for diamonds) or for surgeons. This is the portable, which is a small scale that comes in it's own wood box. c. 1902
