Never seen one of those before, seems a very unusual find!

If you don't receive info on this thread, try posting also in the "What is It?" forum. HAVE FUN! Andi

Thats really cool, I would do something to keep it from further rusting out..like osfo or something. What State was that found in?

Pre WWII, some states, Wisconsin for one, required gas stations to post the gasoline gravity. I believe the gravity is the specific gravity which has to do with the how much lighter than water the gasoline is. "Heavy" gasoline would get you more miles per gallon, but would not works as well with carburetors as well as light gasoline, especially in colder weather. I figure this has to do with how well refined it was, or perhaps what was added to it.

Thanks everyone! It was found near Green Bay Wisconsin just yesterday...only about one to two inches deep. It was in the middle of the woods that our old maps show was a good solid woods since 1938 or earlier. It was however only about 150 yards in from a road. I would love to keep it and save it. Do you have the name of any specific preservation methods.....? Then I will check them out and save this one. ;-) Thanks again! This forum and all your info makes detecting even more amazing!
