Red Bark is perhaps the best-known and valued Dunhill series among other "retired". The Red Bark pipes were produced not for a long time - from 1972 to 1987, and in fact, they are traditional sandblasted Dunhills, but smokers and collectors are still attracted by these pipes and their unusual staining. By the way, the colour was also a subject to experiment - in some years Red Barks were brighter, later - darker again. And this pipe is one of the early Red Barks, an elegant bent from 1975!
The pipe markings are "53 \ DUNHILL RED BARK \ MADE IN ENGLAND15", "(3) R/B". The length is 12.3 cm (4.84"), bowl's height is 4.2 cm (1.65"). External diameter of the bowl is 3.3 cm (1.3"), internal diameter is 1.8 cm (0.71"). The depth is 3.6 cm (1.42") and this pipe weights 32 gr. Briar, vulcanite stem, no filter.
