Hello, I was wondering if anyone knew anything about this bottle, I collect lava lamps and picked up this bottle because it looks just like a lava lamp. None of the other collectors has ever seen a bottle like this but I assume its common. At first I thought Michelob beer but im not sure, its brown glass about 10-12 oz bottle, on the bottom it has a "I" inside a "O" (assuming Owens Illinois ) and has the # 13 and says "REG U.S. PAT OFF", thats about all the info I know I would like to know what it was made for originally. Thank You for the help.
