well shoot, I thought I'd have an answer for you but unfortunately I don't EXCEPT to share this: when I found an old coke bottle embossed with C. S. Barnes I called my local Coca-Cola bottling company and was told it was from a local distributor of "flavored" sodas; in this case it was rootbeer and bottled in 1922. They offered $25.00 for it, I declined the offer as it was one of the first I ever found.
So, maybe call your local coke plant?
