1969 · Regular · Bradford — Case & bottom stamp reference (1969)
Original photograph supplied by Terry Lyons of a 1969 Bradford-made regular-size Zippo bottom stamp (3 left / 2 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 archive retains two 1969 illustration variants; this photographed specimen is not assigned to either graphic without independent variant verification.

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