'''Note:''' All pipes come with a costly fitted black ebonite (is generically known as hard rubber and is obtained by vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. The material has also been called vulcanite, although that name formally refers to the mineral vulcanite).

This version of the spot appears only on the white mouthpieces, for an obvious reason. The stem was made from Ivory in the '20s up to '30s (maybe '40s) and after, from Erinoid. the White Spot stands out with a delicate black ring. Into it is inserted a vulcanite tenon which in turn pushes into the shank's mortice. We have made contact with the Dunhill's factory to know more about the production of the white mouthpiece in the last few years:
