A younger sister of Dunhill Cumberland. "Cumberlands" have been started to be produced in 1979 on the occasion of closing of warehouses on Cumberland Road. The series was very popular and in 1983 Dunhill decided to start a smooth version of this series - a "Chestnut". Surely, you won't mistake its family trait - an unusual cumberland stem. A convincing Chestnut bent exactly from 1983!
The pipe markings are "DUNHILL \ CHESTNUT", "41022", "MADE IN \ ENGLAND 23". The length is 14.5 cm, bowl's hight is 5.0 cm. External and internal diameters of the bowl are 3.8 cm and 2.0 cm. The depth is 4.2 cm and this pipe weights 44 gr. Briar, cumberland stem, no filter.
