A Dunhill Pipe Dating Guide........[转帖]
Alfred Dunhill began to manufacture briar smoking pipes in 1910; the famous white spot first appeared on top of the hand-cut vulcanite mouthpiece in 1915 in order that the customer should know which part faced upwards. At about this same time a one year guarantee against defects was offered on the bowl of each pipe, and to insure against far older Dunhill pipes being replaced under this guarantee a simple dating code, showing the year of manufacture, was devised and stamped onto each pipe bowl. This code is still in use today.
Over the ensuing years great interest has arisen over the "mystique" of the Dunhill pipe in general and the dating code in particular. Pipe collectors, especially in America, pride themselves on having acquired Dunhill pipes in prime condition which were made in the 1920's, 1930's and 1940'x. Some collectors strive to acquire only those Dunhill pipes made between 1920 (when Dunhill stopped buying bowls turned in France in favor of those turned in London at the newly opened Dunhill bowl-turning facility) and 1928 (the year of Alfred Dunhill's retirement). Consequently, much confusion has arisen over the dating code because it has not been standardized over the years, and seemingly minor differences in the code can mean a difference of years, even decades, in the manufacture of the pipe.
Adding to this is the fact that the firm has used a great many special stampings depending on what part of the world to which their pipes were destined, and that sometimes these stampings or codes were used for only three or four months duration.
Leading to even greater confusion is that many pipes were simply stamped incorrectly; at times one part or another of the code is not to be found on a given pipe.
Taking all this into account it should not be surprising that the original and complete dating code list, in possession of the firm's archivist at 30 Duke Street, is some twenty eight pages long. And even if this list was made available it would be of little use to any but the most expert because it can only be used in conjunction with the most precise knowledge of the Dunhill pipe as it has changed in appearance over the years.
But enough of the complications in dating Dunhill pipes. What follows is a "general guide" as to dating; with it the reader should be able to date the majority of Dunhill pipes with which he/she comes into contact.
Types of finish:
1) Bruyere -introduced in 1910; signified by an "A" (meaning' best quality) on the side of the shank through 1975. "Inner Tube" stamped on shank through 1934.
2) Root - introduced in 1930; signified by an "R" stamped on the shank through 1975.
3) Shell - introduced in 1917.
4) Tanshell -introduced in 1953.
5) Redbark -introduced in 1973.
6) Cumberland -introduced in 1980.
Special series: H.W.- "hand, worked". A hand-carved (as opposed to machine-carved) pipe of classic design. "H.W." stamped on shank. Not made after 1930's.
D. R. "dead root". Denotes Dunhill straight grain pipes. The bruyere finish was used on these pipes through 1929; root finish was used thereafter. "D.R." stamped on shank.
O.D."own design". Denotes a pipe designed by the customer and carved to order. "O.D." stamped on shank. Not made after late 1920's or early 1930's. In 1950 a special series of "ODA" pipes was begun and continued through 1975. These were not carved to order.
Collector - denotes hand-turned bowls (as opposed to machine-turned) made from plateau briar. Introduced in 1978.

1951-1960 A single small digit following the "D" in "ENGLAND," usually underlined, denotes the year of manufacture. Thus, a pipe stamped ENGLAND 1 was made in 1951, whereas ENGLAND 0 indicates a manufacturing date of 1960.
1961-1970 A single uniformly-sized digit following the "D" in "ENGLAND", denotes the year of manufacture so ENGLAND1 was made in 1961 while ENGLAND0 was made in 1970
1971-1999 A pair of digits following the "D" in "ENGLAND" denotes the year of manufacture. However, the underlining and size of the digits varies. For example, ENGLAND11 was made in 1971; ENGLAND20 was made in 1980; ENGLAND30 in 1990; and most recently, ENGLAND39 was manufactured in 1999.

有關Dunhill的各年代編碼與專利系列內容，可參考由John C. Loring所寫的一本
專門記載的書「The Dunhill Briar Pipe -- The Patent Years and After」 字斟句酌，实在太难了。词不达意，云山雾罩；一旦有误，毁人不浅。
John C. Loring 的“A Four Volume Compilation of Dunhill Catalogs & Patents”，想不明白都不行。very good。
In 1912, Dunhill invented and patented the "inner tube", an aluminum insert designed to keep the pipe "innards" clean; in 1915, the "white spot" appeared to help the customer know which side of the hand-cut vulcanite stem should be uppermost; 1917 saw the introduction of the first Dunhill sandblast - the "shell".
In producing the "shell", Dunhill used only Algerian briar, then in great abundance, because it had a softer character than the Italian briar used in the smooth "bruyere" finish. This soft character, in combination with the heat derived from Dunhill's unique oil curing process, led to an unusually deep and craggy sandblasted pipe. In the early years of production, Dunhill would not even stamp shape numbers on his "shell" pipes, since the shape of identically turned bowls varied so after curing and sandblasting.
Dunhill's "root briar" was introduced in 1930 (by this time, Alfred Dunhill was two years into retirement and his brother Herbert had charge of the business) and the light brown finish proved highly popular in America, less so in Europe. Next, some twenty three years later, came the "tanshell" a sandblasted Sardinian briar with a tan or brown finish. It took twenty-six more years before another finish - the "cumberland" - appeared. The cumberland is also sandblasted, has a dark brown finish, a smooth beveled top, and a bi-color vulcanite stem (this same stem first appeared in 1930 on the root briar).
As I mentioned previously, no Dunhill pipe was completely fashioned in England until 1920 when a bowl-turning section was opened in the London factory. Before this time "turned" but unfinished pipe bowls were imported from France and then finished, oil-cured and, in the case of "shells", sandblasted in London.
The briar situation must be investigated in order to compare the new Dunhill pipe with the old there have been changes. Originally, Italian briar had been used for the "bruyere" and "root", Algerian for the "shell", and Sardinian for the "tanshell". The age of the briar used, averaged between 60 and 100 years. In the 1960's, the briar situation changed drastically. The Algerian supply slowed to a trickle, and the Italian government declared that its briar could only be used by pipe makers within its borders. To that time, Dunhill had a virtual monopoly on briar supply; now it had to search for new sources and could no longer reserve one type of briar for one pipe finish
This change was readily apparent in the "shell" finish. Deprived of Algerian briar, Dunhill had to use Grecian briar, a harder variety, and so the "shell" pipe now received a more shallow sandblast. As well, the wood was less aged between 50 and 80 years. Additionally, the briar burls were smaller and had more flaws, so there were less perfect bowls being turned, and - more waste! Conversely, the new briar was harder, lighter, and had much better grain than the old. Dunhill was never known for beautiful grain patterns in its smooth-finished pipes, but those produced today are outstanding when compared with those of twenty years ago. In the manufacture of a quality pipe, much attention is paid to making and fitting the stem, or mouthpiece.
