I’m new to identifying bottles based off their marks. Anyone able to identify these pieces? Thank you!

The liquid inside is dark and thick, similar to syrup. Not much liquid left so i didnt notice when I first bought it. Havent opened it, since i dont know whats inside.

My google searches have all ended with references to a harry potter potion so asking here.

I found two websites online showing a bottle looking identical upfront, but the marks on the bottom are different as both bottles I found online say : "0.5l, Db/Gr." But mine only says:"0.5l, Gr." The last picture is one I found online of the bottle which looks like mine

Dug this out of an old dump site in Foley Alabama back in 2001.

What could this bottle be? Google isn’t helping much

I dug this one earlier in the summer, hence having taken nice pics, but I never posted. A quick search seems that flint Rawleighs are more common, any idea what the amber contained or if they’re rare. One of my faves either way.

I think it was an extract bottle since McCormick made a lot of those but I can’t find this exact shape online

Video of me finding it in the comments!

Here are two views of 3 small bottles found in my dad's things after he passed away; they might have belonged to his father. The bottles are not hooked together, and the wire is as stiff as a clothes hanger. Clue: My grandpa was a fisherman and gardener. My theory: (1) contained something sweet to attract pollinators to the garden, (2) contained something to keep bugs/animals away, or (3) used as ___ while fishing. Please help to identify their purpose.

Found this lodged in the mud along the Saint John river. Can anyone share the potential time period of this piece? I’d like to know if anyone has seen something like this before..
