WWII Phase: Difference between revisions

No date code or any other nomeclature, like the inner tube, for example. According to the available historiography, the 1341418/20 patent begins to appear in 1920, almost always followed by another patent, as an example: PATENT MARCH.9.15 1341418/20. In rare cases it appeared alone. We recently had access to a pipe bought at that period (unsmoked!), perfectly aligned with Loring's hypothesis. Take special attention to the flyer (that reminds us of the war) that says: <q>'''Arrived Safely - Thanks to Sea Power'''</q> and that reminds us of the war.

Until circa mid-1936 the nomenclature was done with the possessive, i.e. "Dunhill's Shell". After this period the possessive was removed, becoming "Dunhill Shell". Thus, as the pieces in question are already from the time of possessive suppression, we only have to assume that they are later than 1936. The only pieces found with this patent date to the 1930s (1933 specifically), returning to appear 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.
