Vauen Mc TWEN 318 Sandblast Bent Brandy, Vest Pocket — Late 20th to Early 21st Century

The pipe is fitted for a 9mm filter, the system most closely associated with German pipe making. Vauen, based in Nuremberg, is widely regarded as Germany's oldest pipe manufacturer, tracing its lineage to the mid-nineteenth century, and the firm played a central role in popularising the 9mm activated-charcoal filter that became the standard bore across German and much of continental European production. A 9mm chamber in the shank is therefore both a functional feature and a marker of the pipe's national manufacturing tradition.

Dating rests on the line and shape stampings rather than any factory date code, as Vauen's serial-production pipes do not carry year marks. The Mc TWEN designation together with the three-digit shape number 318 identifies the pipe within the company's modern catalogue system, and the 9mm fitment situates it firmly in the era of standardised filter production. On this basis the pipe is bracketed honestly to the late twentieth or early twenty-first century, recorded from a German estate source, with the shape number preserved as the primary anchor for future comparison against Vauen's published shape charts.
