1976 · Regular · Bradford — Case & bottom stamp reference (1976)
Original photograph supplied by Terry Lyons of a 1976 Bradford-made regular-size Zippo bottom stamp. The documented code pattern is 3 left / 3 right forward slashes. Reflections, wear and shallow impressions can hide the marks; compare the whole stamp. Photographs establish a documented collector example, not a factory certificate. A separately photographed In Quiet Detail reference is retained; this is an independent Terry Lyons example.

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