I don't know much about Georgia bottles, but I would think it would be a John Ryan bottle. Although... James Ray and Henry Kuck were there early as well.
most likely the pottery Ryan followed by Philadelphia xx porter & Ale.in a blue green.1840s. there are about 25 or 26 deferent John Ryan bottles out there and a dozen deferent colors.
Could be. E. D. Meyer was in Augusta in the 1840s. Only 7 bottles known. Tough to say who was earlier of the two. Maybe someone has already researched that?
