This zippo by it's mark can be any where from !950 -1958, correct zippo letter's and Patent number,can't tell if has dots'to left or right,but either way this is a old and rare zippo,even the insert seems to show correct patent,I have some ,the are highly collectible ,just the tin looks new,but that does not take away from the value of the lighter, you can tell from the 50's because of the slant up of the Z, this is a good auction will make nice addition to any collection even if used
to be correct could be 60's to early 70's still at the very least 73' making it at least 46-47 yrs old,just can't till if it has dot's or IIII type of marks marrks
