Zippo lighter restoration - Vietnam War repair Long Bin 1967-68

Zippo lighter restoration from the Vietnam War Long Binh post. This time I do a full restoration and repair of a very dirty and rusty Zippo lighter that was sent to me to restore. I actually don’t know anything about this lighter because the person who send it was anonymous, but I assume that part of it is real. The Zippo lighters outer case seems real enough and was way more damaged and elder looking than the inner part. There was a very vague Zippo brand name in the bottom lighter case with serial number PAT 2517181 (Maybe the 8 is a 0?) The inner part of the Zippo was surprisingly shiny, after getting some wd-40 rust remover, considering it should be over 50 years old. If you know anything about this Zippo, if it’s a fake Vietnam war lighter or the real deal then please leave a comment below. I really like to know. Thanks. The inscription on the lighter was VIETNAM LONG BINH 67-68 WE HAVE DONE SO MUCH FOR SO LONG WITH SO LITTLE THAT WE NOW CAN DO ANYTHING WITH NOTHI
