At first, this rounded marking was thinner and made in celluloid, a species of an acrylic predecessor, which was used until the mid-40, when it was replaced by high-quality acrylic. Because of its appearance, it was defended for years and for many, that the point was made in ivory. However, it is a widespread legend for years, as evidenced by the information and tests executed in the Pipes Magazine Forum, in a post called "Dunhill White Spot Drama". Up to 1976, all the stems were made by hand. They have now been machined due to labor costs.

==== About Inner Tube ==== <!--T:49-->
In the early XX century, many pipes were left aside after a long period of use, due to obstruction of the suction duct that clogged for lack of maintenance. Alfred Dunhill, in 1911, found a reasonable solution to the problem by inserting an aluminum tube that should be replaced as soon as there were signs of clogging. In this way, the use of the pipe was prolonged. The Inner Tube was heavily produced until the 30s. With the advent of the  "Scovillions" (or cleaners) were gradually falling into disuse.
*5861/12 was the first patent registered. However, there are other patents for these same tubes, with records in different countries. Examples: 1130806/15-158709/14-116989/17-1343253/20-197365/20-491232/19.
