This is a brand new Museum Quality reproduction octane tag. This was used on the WWII fuel jerry cans to know the difference between aviation fuels and vehicle fuels. This simply bends around one of the three legs of the handle.  Excellent little detail item. I took a picture of one next to a house key so you can see the size of this item.  These are from MV Spares so you know they are 100% correct.  Yes, We combine shipping on multiple items.
