Very little is known about the company. According to the albums the company was founded in 1760 in Amsterdam as Hermann Oldenkott, with since 1819 a subsidiary in Ahaus (Germany). Probably the factory had some other factories as well, as in 1838 August Kersten from Rees (Germany) bought the factories from Heinric Oldenkott in Elten (Germany) and Weesp (Holland). It is, however, not clear whether these were part of the same company as the original Oldenkott company. This German company increased rapidly and became one of the largest German tobacco companies. In 1929 the factories from Hermann Oldenkott in Ahaus and Neuss (Germany) were bought by the German Oldenkott company. The German company also produced pipes since 1932. In 1972 the German company was bought by the Dutch company Niemeijer. Tobacco production ceased in 1974 and only pipes were still made. In 1987 the German pipe company was bought by the Kersten family again, but closed in 1992.
The pipes was also machine made and in general of mediocre quality. The most important pipes of Oldenkott was the so called "Porsche" design pipe. The bowl was turned like the motor block of a racing car an was laquered with a silver-grey colour. Today this special pipes are very rare and expensive. If have no idea of the grading system of Oldenkott.
Independent on what I say about the quality of both Oldenkott and VAUEN, the pipes are know as good smokers.
