Hi and welcome
You have a 1960s or 70s soda bottle.
I found references to a S & OK Brand soda from Butterfield Bottling Co in Greatworks, Maine. This bottle has an ACL (painted) label and to a OK Bottling Works, Rochester, NY embossed bottle.
There is not a whole lot of value here but it would be an interesting research project to find the bottler. Will let you know if I come across any further info.
