This is a genuine authentic zippo.From the Vietnam war era 1968, as verified by a local person who looks at watch's and lighters.This was my grandfather's. As per the three lines on the bottom , this indicates that it was made approximately 1968-1970 in bradford , pennsylvania. This has been stored my grandfather's personal attacks for many years.So there is some rust on the spinning wheel that strikes , and it needs a good cleaning , but should still work. It is a classic design and unengraved.
