Ok, hang on..
Owzat?
Nope, nope and nope. But I can see the similarity. Its a hard one and no mistake. It is not an engine part.
It's an emergency spare part..You would use it on a car, yes.
It kinda looks like it coud be an end view of an emergency road flare... but that ant somptin you woud use "on" a car.???
So are you willin to tell what the diameter of the item is.???
Does it require a tool to make use of it.???
