The “12” Stack from Dunhill is an old shape: In an earlier form it was the basis of one of the “windshield” pipe designs that Alfred Dunhill himself once marketed as ideal for automobile drivers. This Group 4 is a more traditional rendition of the shape, adding a bit of stoutness as well as overall increase in scale and chamber to the form when compared to Group 2 and 3 versions. One of Dunhill’s more recent finishes, the Amber Root was introduced in 1995. Like the Root Briar, it showcases a smooth stain, accentuating the briar’s natural grain in traditional style. Typically auburn-hued, the Amber Root is often a touch darker in color than that of the Root Briar, pairing handsomely with the jet-black stem for an aesthetic that combines the grain definition of the Root Briar finish with the darker, smokier tones of the Bruyere. This pipe is a great addition to any tobacco pipe collection. It has been lightly smoked and is in excellent shape. Chamber Diameter – 20 mm. Chamber Depth – 30 mm. Length – 139 mm.
