However, the destiny disposed so that some time (1978-1988) the Charatan company belonged to Alfred Dunhill, and Charatan pipes were produced in parallel at the facilities of both companies. And the recently introduced marking "DC" (Double Comfort, it's a specific form of a stem) was often treated as Dunhill's Charatan.

External and internal diameters of this bowl are 3.9 cm and 2.2 cm. The depth is 4.0 cm and this pipe weights 38 gr. Briar, vulcanite stem, no filter.
