Vintage 1966 Zippo Lighter with Insert

VTG 1966 Zippo Lighter w/ Insert This auction is for a vintage 1966 Zippo. This features 4 slashes and 4 slashes on the bottom. As you can see the front design in nearly gone. I’m not sure if the insert is original or not. This does spark but needs fluid. We don’t have the box. If you have any questions or concerns before purchasing please message me and I will get back with you asap. Thank you!
