I was curious if anyone out there could tell me more about my bottle mold. It is heavy duty, it probably weighs 30lbs, it is stamped with raised letters coca-cola on one side, and coke on the other, with return for deposit, in the hobbleskirt design. I know this is a shot in the dark, I plan on keeping it, but if anyone could tell me the years it was made, it would be greatly appreciated. I will upload photos later.
