Construction features documented for 1979
Typical US regular-production chronology from independent collector research by Hardi Döhler. The ranges overlap, and Canada, Slim, Replica, Sterling, Japan-market and special editions may differ. These are supporting observations, not a definitive date determination.
Case shapes
- Postwar recessed-bottom profile 1947–2026 · broad · Source: Hardi Döhler
The familiar recessed-bottom case profile develops in the postwar years; this alone cannot distinguish later decades.
Present-day cases, replicas and special lines can depart from the usual form.
Case metals and finishes
- Brass as common regular-case substrate 1954–2026 · broad · Source: Hardi Döhler
Chrome-plated brass becomes typical again in the mid-1950s; special materials and later editions are exceptions.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Hinge development
- Five-barrel hinge with unequal widths 1956–2005 · broad · Source: Hardi Döhler
Later five-barrel hinges generally have an uneven barrel-width pattern. This broad clue cannot determine a precise year.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Insert materials
- Chrome-plated sheet-steel insert 1953–2026 · broad · Source: Hardi Döhler
Chrome-plated steel construction with a seam is typical of later regular inserts, but special and premium variants differ.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Insert lettering
- Vertical insert lettering 1959–1999 · broad · Source: Hardi Döhler
Vertical inscription layouts are common across later twentieth-century inserts; compare typography and code patterns.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
- Both insert faces carry text 1976–2026 · broad · Source: Hardi Döhler
Two-sided marking layouts appear through later insert generations, alongside evolving date-code placements.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Chimney construction
- Open-sided 16-hole chimney 1947–2026 · broad · Source: Hardi Döhler
Sixteen holes and an open wheel-side chimney wall become typical from the late 1940s onward.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Cam springs
- Wide straight cam spring 1971–1988 · transitional · Source: Hardi Döhler
A wider straight leaf spring is typical of much of the 1970s and 1980s.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Flint-wheel cuts
- Cross-cut flint-wheel teeth 1946–2026 · broad · Source: Hardi Döhler
Cross-cut flint-wheel pattern becomes typical after the war, with possible overlap and replacements.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Flint-wheel rivets
- Solid flint-wheel rivet 1964–2026 · broad · Source: Hardi Döhler
Solid rivets become typical from the mid-1960s onward.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Felt pads
- Unprinted light-coloured felt pad 1947–1992 · broad · Source: Hardi Döhler
A plain pale rectangular felt pad is documented across many decades; replacement pads limit its dating precision.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Wicks and packing
- Pre-copper-wire wick construction 1933–1980 · broad · Source: Hardi Döhler
Older wick styles can differ from the later copper-wire-interwoven wick; repairs commonly replace wicks.
Some historic wick materials may contain asbestos; avoid disturbing uncertain old material.
Insert construction evidence

Interpretation: References may cover multiple years. A documented insert date is not proof of its case production date, and special Replica stamps require separate interpretation.
