Any clues as to who made this and what it was for? Dug in an 1880 privy. C & S on one side. Another side has Bryan O. And another side has I. & P.O. Thanks for the help. Jgas.
May be a very old ink bottle some ink bottles can be pretty valuable. I’ve never seen anything like it.
The C&S may be Cannington, Shaw & Co... just a guess.
Looks like what was called a Stoppered Squat French Square in the glass industry from 1906 Illinois Glass Company Catalogue https://sha.org/bottle/igco_1906.htm
