Green glass beer type bottle

Found several of these, no other markings on the bottom except 30N and that’s underlined with a embossed line. Just trying to figure out company, product or what these once were. Any help is always greatly appreciated!

I found this document that might be your answer. On page 15 there's a table of logos and bottle markings. If I understand it correctly, this was made in 1930 by the American Bottle Company at their plant in Newark, Ohio. If you're in Ohio or a bordering state that could very well be it. If this is right, 1930 was during Prohibition so this can't have been alcohol. Beyond that, I don't know.

I'm impressed @backyardarcheologist ! Good detective work.

There is the manufacturer and then there is the product. From the product point of view, this is a very, very common generic beer bottle that once had a label.... could have been any brewery.
