 ==== Shell ==== <!--T:50-->
+The documentary history of Shell's inception is essentially limited to patent applications — there are no pages in catalogues or advertisements promoting product blasting at the time. These requirements show that the preliminary application of the English patent (Patent No. 1484/17) was lodged on 13 October 1917, with a request completed half a year later, on April 12, 1918, followed by the granting of the English patent on October 14, 1918, shortly before the end Of the Great War on November 11th.
+The American patent (Patent No. 1,341,418) application was prepared and filed before the English concession, between September 19 and October 14, 1918. The American patent was granted more than a year later, on May 25, 1920. Canadian documents were behind the U.S. in a year, with application of 1919 and the concession in 1921.

-A deep craggy sandblast with a black stain finish. Duhill pantended the sandblast finish in England in 1917 (Patent No. 1484/17) and the U.S. in 1920 (Patent No. 1,341,418). See [[The Art of Sandblasting]], and by R.D. Field, for in depth look at Dunhill's revolutionary new finish. The deepest and craggiest finishes were from Algerian briar, which is softer and yields more to the blasting. These are found in circa 1920's, 1940's, and 1960's Shells. The pipes were double blasted until the 1960's, and then the double blast technique resumed in the 1980's calling it the "Deep Shell" finish. During the 1960’s and 70’s Dunhill could not acquire the Algerian briar. Consequently, the company’s sandblast pipes were much shallower and less distinct. Once again Dunhill showed itself to be innovative, inventing the “double blast” technique to bring about a deeper blast even with harder briar. The black shell sandblast finish uses a stain the was developed for the color, not the taste. Some enthusiasts experience them having a more bitter taste, even when judiciously smoked.
