WWII Phase: Difference between revisions

Until approximately mid-1936 the nomenclature was done in the possessive, i.e. "Dunhill's Shell". After this period the possessive was dropped, becoming "Dunhill Shell". Thus, as the pieces in question are already from the time of non-possessive nomenclature, we can assume that they are post 1936. The only pieces found with this patent date are from the 1930s (1933 specifically), and return in the beginning of the 1940s (up to 1945, perhaps), when it was replaced by 417574/34. Some pieces have the same patent in the beginning of the 1940s (1941/42), however, with the suffix "U.S.", namely: U.S. PATENT 1341418/20, being destined for the North American market.
