The lighter has been engraved in NAM likely by the soldier himself and not by one of the tailor shops.
The lighter has been engraved on the side by the previous owner, "Ron Wilson"?
I am not sure if the insert is the original one to the Zippo... Take a good look at the pictures and ask questions!
The patch has been removed from an uniform, but is in great used condition.
This is the REAL DEAL and NOT some cheap "after-war souvenir fake"!!!
Immediate payment after the auction is much appreciated
