Vintage Vietnam War Cu Chi 65-66 USMC 1st Marine Corp. Engraved Lighter

Description

Vintage Vietnam War Cu Chi 65-66 USMC 1st Marine Corp. Engraved Lighter. I do not know when this lighter was made, by who or engraved. Looks older and emblem on front looks to be a thinner lighter emblem and not something made from a insignia crest. Has scratches, etc on finish. I have been told they sold  lighters like this in Vietnam after the war. However, may be older and even the real deal. I do not know. It has no brand name on the bottom. The word Function looks misspelled on the engraving. Buyer be the judge. Lid seems tight and it opens and closes with a snap. Has no fluid in lighter. Has 1st Marine emblem on front and engraved back(see photos). It is as found and selling as is condition.
