I think they may come from near by, they were a soda pop so probably something people would buy from local companies? I'll do what you say and if there is still no info I will ask someone like an antiques dealer by me about it and maybe they will know.I would suggest cleaning it up a bit(soap and water) and take better pics of the bottle and the bottom. Also what city or town is embossed on it? Seems common if you are digging a bunch of them? I wouldn't be upset on the price. It is a good find.
