Vauen Dr Perl 3368 Smooth Straight Billiard, 9mm Filter

This reference example documents a Vauen Dr Perl straight billiard, shape number 3368, presented in a smooth finish and fitted with the maker's characteristic 9mm filter system. As a German estate pipe, it carries a history of prior use, recorded here as a matter of fact within the attribute checklist. The house occupies a distinctive place in pipe history as the principal champion of the 9mm activated-charcoal filter, a system marketed under the Dr Perl name. The Dr Perl filter, seated in a widened mortise between shank and stem, draws smoke through a charcoal cartridge intended to moderate moisture and condensates; the design became so influential that the 9mm bore is now the dominant filter standard across the German-speaking pipe market. Pipes bearing the Dr Perl designation are therefore emblematic of a specifically Continental smoking tradition, one that diverges from the unfiltered Anglo-Danish mainstream. The billiard is the foundational shape of the classical repertoire: a cylindrical bowl set at roughly a right angle to a shank of comparable length, with a straight stem completing an uninterrupted line from bit to bowl. This example follows that canonical straight configuration, its smooth finish leaving the surface of the stummel fully exposed. Dating a Vauen presents the archivist with a familiar limitation: the firm does not stamp its production with factory date codes, and shape numbers such as 3368 identify the model rather than the year. The stamping establishes what the pipe is, not when it was made. Accordingly the record assigns an honest, deliberately broad bracket within the twentieth to twenty-first centuries, resting on the owner's attribution and the reported markings.
