I've just begun doing research on 3 little bottles which I dug out of an old farm trash site about 35 years ago, and I need help. The only bottle which seems possibly to be collectible is a 4-ounce Old Quaker bottle. It does not bear the "Federal Law Prohibits...", so it's pre-1935. Prowling the internet has revealed MANY Old Quaker bottles available in larger sizes, but I can't even find a listing of the 1/4-pint version. Does anyone know anything about this piece?
