Construction features documented for 1997

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 cam spring with tapered wheel-side end 1988–2026 · broad · Source: Hardi Döhler

    Later springs show wheel-side shaping/tapering; date the insert using inscriptions and other details as well.

    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

  • Black LIFT TO FILL print without spare-flint hole 1993–2001 · transitional · Source: Hardi Döhler

    The black printed LIFT TO FILL pad without an extra hole is a useful transitional clue.

    Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.

Wicks and packing

  • Copper-wire-interwoven wick 1980–2026 · transitional · Source: Hardi Döhler

    Copper-wire reinforcement becomes common around 1980; wicks are consumables and cannot reliably date a case.

    Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.

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.
