I’ve done an evening’s worth of research, but figured I’d throw this out there in case anyone else has better ideas on how to look.
I found what I believe to be a vintage medicine bottle. An evening of research found this information, though it could be wrong:
Brand: Owens Illinois
Plant: 23 (Los Angeles)
If I’m reading it correctly, which I doubt, it was made in 1930 or 1940 in mold 6878-A, slot 3
Edit: The bottle is about 2.5" tall and about 1.5" at the base.
