This coca cola bottle appears to be a Pat-D that type dates between 1938-1951, i have been told this is a 1950 and was made by Owens Glass-works in Worcester Massachusettes. The perplexing part is that this appears to be made out of carnival glass. The coloration is inside, outside, and throughout the bottle. My thoughts are that it was part of a promotion, or a limited release, but I can not find any information about it. any additional information would be greatly appreciated.
