Zippo · 1967 — Case & bottom stamp reference (1967)
Original photograph supplied by Terry Lyons of a 1967 Bradford-made regular-size Zippo bottom stamp (4 left / 3 right vertical bars). Compare the entire stamp, including registered mark, patent wording and the position of each impressed mark; wear, reflections and shallow strikes can hide individual marks. The photographed case is a collector reference, not factory provenance. The patent wording is visible on this photographed early-style 1967 stamp; the patent-free 1967 variant remains a separate reference.

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