A rescued Comoy’s pipe from the late 1930s. The extremely popular Grand Slam series was started in the 1930s (according to the one of legends – in 1933, and it was named so in honor of success of a British tennis player) and was produced up to the 1970s. The patent system with marking existed till the beginning of the 1950s. In this case the Country of Manufacturing stamp is really helpful – such a marking “MADE IN ENGLAND” (in a circle and without “LONDON”) was specific only for the 1930s.
The pipe markings are “COMOY’S \ GRAND SLAM \ PATENT”, “MADE \ IN \ ENGLAND” (very hardly visible), “US PAT \ 2001612” (already difficult to read), “126B”, “*2”. The length is 14.2 cm (5.59″), bowl’s height is 4.1 cm (1.61″). External diameter of the bowl is 4.1 cm (1.61″), internal diameter is 2.4 cm (0.94″). The depth is 3.4 cm (1.34″) and this pipe weights 39 gr. Briar, vulcanite stem, no filter. The pipe required more efforts and patience than usual: the lost stem was replaced with a new one made of fresh piece of vulcanite, the chip off part of the shank was fixed and clamped with the nickel collar for the maximal reliability, the chamber was rounded (though it looks a bit of center).
