Vauen Dr. Perl Sandblast Straight Billiard 4234, Vintage (Era Undetermined)

This reference example is a straight billiard from Vauen's Dr. Perl line, finished in sandblast and carrying the shape number 4234. The billiard is among the most enduring forms in pipe making: a cylindrical bowl set at or near a right angle to a straight shank of roughly equal length, prized for its balance and for the clean geometry that makes it a benchmark against which other shapes are described. A sandblast finish, produced by blasting the stummel with abrasive media, strips away softer wood to reveal the grain in relief, yielding a tactile, rugged surface that is lighter in the hand than an equivalent smooth-finished piece. The firm is most widely associated with the 9mm filter system it pioneered, and the Dr. Perl name is central to that history: Vauen markets its activated-charcoal filters under the Dr. Perl designation, and pipes in this line are built around that filtration concept, a hallmark of German pipe-smoking culture more broadly. Dating the example rests on the owner's characterisation of the pipe as a vintage German estate piece together with the stamped shape number 4234. Vauen shape numbers identify the model within the factory's catalogue rather than a year of manufacture, and the firm did not employ a systematic date code on pieces of this kind; consequently the numbering places the pipe within Vauen's production range without fixing a precise year. On the evidence available, the honest conclusion is a vintage-era attribution of undetermined date, held in the archive as a representative document of Vauen's Dr. Perl sandblast billiard production.
