No staining just a natural finish! This is an exciting indeed example of the good old fashioned English pipe carving art. The pipe was made in 1940, already on the beginning of the Wold War II, but it shows the same approach, the same sense of taste and the same highest skills which made Dunhill a superstar in the smoking pipes Wold just from the very beginning!
The pipe markings are "R", "DUNHILL \ LONDON", "MADE IN ENGLAND 0", "U.S. PATENT 1343253/20", "501". The length is 15.4 cm (6.06"), bowl's height is 3.7 cm (1.46"). External diameter of the bowl is 3.6 cm (1.42"), internal diameter is 2.1 cm (0.83"). The depth is 3.2 cm (1.26") and this pipe weights 27 gr. Briar, vulcanite stem, no filter. The stem is newly made of the fresh piece of vulcanite so we can consider the pipe as a "partially unsmoked" :-).
