Looks like an old military fuel drop tank. Back in the late 40s early 50s racers turned old drop tanks into lakes racers. Think Bonneville in Utah. Lookin Good!

Thanks Rob. RIDE SAFE.
I should have got a pic from the front also. It had something about the Bonneville Salt Flats written on it. I wanted to wait till the owner came out so I could ask him about it, but I was hungry.
