Original-Gossen 150 V and 250 V Laboratory Series Resistors – Vintage Pair

€145,00 EUR
An intriguing pair of vintage laboratory series resistors, offered as Original-Gossen, marked 150 VOLT and 250 VOLT. These technical collectibles combine dark housings with perforated metal covers and substantial fork-shaped terminals. The 150 V example bears the ORIGINAL-GOSSEN name alongside the historic D.R.G.M. and D.R.P.a. markings. The seller identifies these as prewar German components dating from approximately 1935–1943, made by Gossen of Erlangen. The exact production date and the provenance of both components have not been independently verified. This type of series resistor was used to extend the voltage measurement range of compatible electrical instruments. The voltage figures are the markings on the components, not confirmation of tested performance or present-day electrical safety. The seller describes the dark housings as early Bakelite or phenolic resin; the material has not been independently examined. Their industrial design and historic lettering make the pair an appealing addition to a collection of early laboratory equipment or German electrical instruments, or a distinctive technical display in a study or cabinet.
