Found this bottle in an abandoned lot a few days ago. The symbol on the side looks like a "3" with a ghost (if it were a coin I'd say it had been double-struck) and a "III" next to it. Some kind of generic med by Owens?
Base markings: "6 <0> 2" over "4".
The "funny 3" is actually the apothecary symbol for fluid ounces and the Roman numerals next to it designate the number of fluid ounces. In this case, your bottle held 3 (iii) fluid ounces.
