This is for sure not a WW2 item !
A “Zippo” model lighter in light used condition.
Has to be filled with liquid gas.
The picture shows a plain green lighter and a circle with the text “the u.s. army”
The underside of the lighter is marked with “Z16”, but don’t know what it means.
You can use it in a lighter collection, military display or just simple for every day use.
