Dunhill pipe dating
Dunhill pipe dating uses the small date suffix with the shank wording, finish and shape code; a shape number is not itself a year.
Suffix beside England
A small raised or full-size number after ENGLAND belongs to a period-specific date sequence. In the later system, 1960 is a base year and the suffix is added to it; 15 can denote 1975. Earlier periods use different single-digit and patent-era readings.
What to check next
Copy the suffix size and position, PATENT wording, finish and shape code. Keep a replacement stem’s white spot separate from the shank stamps. Identify the marking period before applying the later arithmetic to an older one-digit suffix.
