1972 · Regular · Bradford — Insert reference (1972)
Regular · 1972: The case and insert belong to a documented 1972 Bradford example. The case bottom stamp is shown separately. Other insert variants may overlap. Zippo · 1972: Insert front, reverse and chimney-top photographs accompanying Terry Lyons’s 1972 Bradford regular-size Zippo. Lettering and construction are real photographic evidence; insert replacement and overlapping production periods prevent a guaranteed factory pairing or exact insert manufacture date. The reverse face is photographed without the later two-sided text layout; this single specimen is not a universal dating rule.

Historical variants and original source records
Independent sources and distinct stamp layouts are preserved as individual photographs, not additional main cards. A pictured example alone cannot establish that every lighter from the year used the same construction.

Dating caution. Case and insert can have different manufacture dates; inserts may have been replaced. A single feature does not establish authenticity.
