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.
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.
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.
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.
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.
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.
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.
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.
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.
Solid rivets become typical from the mid-1960s onward.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
A felt pad with black LIFT TO FILL text and a spare-flint hole is a common later version.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
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.
