Historical dating note
A real 1950 Bradford example supplied by Terry Lyons documents a brass case with nickel insert. This is specimen-specific photographic evidence, not a rule that every 1950 Zippo used the same material combination.
Historical year lookup
Zippo 1950
Historical Zippo references associated with 1950: 3 case/bottom stamp entries, 3 insert entries, and 2 photographed examples. Date codes, materials and insert construction should be assessed together, especially for transitional years.
Historical context and cautions
Canadian production note
PAT. PEND. was used until around the end of 1950. Changeover pieces can pair a PAT. PEND. case with a newer Patented 1950 insert as old stock was exhausted.

Construction features documented for 1950
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
- Return to chrome-plated brass 1948–1951 · approximate · Source: Hardi Döhler
Chrome-plated brass bodies are documented across the late 1940s and into the early 1950s.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Hinge development
- Nearly equal five-barrel hinge 1949–1956 · transitional · Source: Hardi Döhler
Five-barrel hinges with relatively even barrel widths appear from late 1949 onward.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Patent and bottom-stamp wording
- PAT. 2032695 case marking 1936–1953 · transitional · Source: Hardi Döhler
PAT. 2032695 is associated with many late-1930s through early-1950s bottom stamps, with layout variations.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Insert materials
- Nickel-silver insert 1946–1951 · transitional · Source: Hardi Döhler
Nickel-silver inserts are documented for the immediate postwar years, including Terry Lyons’s 1946–1949 specimens.
Typical Bradford-made regular lighter; exceptions and overlapping production runs exist.
Insert lettering
- Patent text on one insert face 1943–1959 · approximate · Source: Hardi Döhler
One-sided patent/instruction layout is common in several mid-century insert families; the exact layout evolved.
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
- Humped leaf cam spring 1937–1957 · transitional · Source: Hardi Döhler
The arched/humped leaf cam spring is documented across several prewar and postwar decades.
The photographed 1947 Terry Lyons example has a modern replacement spring; never infer 1947 spring design from that component.
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
- Hollow flint-wheel rivet 1933–1963 · transitional · Source: Hardi Döhler
Hollow flint-wheel rivets appear through the early 1960s; later examples may carry replaced components.
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.
Case construction evidence
- 1949 onward 5-barrel hinge — Known period: 1949–1955. Evidence: secondary. Sources: Glen's Zippo Page.
- Up to 1955 equal five-barrel spacing — Known period: 1949–1955. Evidence: secondary. Sources: Glen's Zippo Page.
Insert construction evidence
- 16-hole chimney — Introduced during 1946; not useful as a precise clue on later inserts. Known period: 1946–9999. Evidence: secondary. Sources: Glen's Zippo Page.

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.
