The "33" shape is one of Dunhill's rarer designs, and it's one of the few that takes a variety of forms depending on its rendition: Sometimes it presents a more Volcano-like shape, while other iterations are more rounded and Brandy-esque, like this Group 4 version. Regardless, it always features a flat, defined heel and upward taper, with this piece featuring a considerable taper and voluptuous base. The extra-slender shank and slightly elongated stem accentuate the bowl's curvature, poising it on the end and adding elegant sleekness to the profile.

The Shell Briar's addition to the Dunhill catalog was a pivotal moment in pipe smoking history. Before 1917, pipes with sandblasted finishes had never been made, and Alfred Dunhill's innovative mind created arguably the most popular finish for pipes today when he unveiled the Shell Briar. With its dark, reserved color palette and delightful texture, it's no surprise that it's still wildly popular over a century later.
