A distinctive Dutch scientific instrument set comprising two glass hydrometers, a Rijks-Honderddeelige thermometer, and an accompanying paper correction table, housed in a fitted, fabric-lined wooden case. Fine graduations, calligraphic inscriptions, and contrasting black and pale-colored ballast bulbs give this set a striking presence as a collectible associated with alcohol measurement and excise inspection. According to the identification supplied by the seller, the instruments are associated with Instrumentenhandel v/h G.B. Salm Amsterdam, based on the Keizersgracht, and W. Geissler Amsterdam. Reported inscriptions include “Rijks Honderddeelige Alcoholweger,” “Temp: 15° Celsius,” “Instrumentenhandel v/h G.B. Salm. Amsterdam,” and “W. Geissler Amsterdam.” According to the supplied reading of the documents, hydrometers No. 185 and No. 94 are associated with 1883 and 1881 respectively, while thermometer No. 43 bears the date 1923. These are reported document and instrument dates, not independently established manufacturing dates. Leeuwarden and Inspectie Nijmegen are also mentioned in the supplied identification.
