4 Various Bottles

[valhom]

Hey guys. I have a few different bottles here. I don't know what era/date they are all from. If you could please help me: identify what the bottles might have been used for; what era they came from; and possibly give me your best appraisal on its worth. Thank you in advance.

Bottle #1:

Measures almost 6" tall

Bottle #2:

Measures about 9" tall

Bottle #3:

Measures a little over 8" tall

Bottle #4:

Measures about 6 1/2" tall

*It still has some type of dark liquid inside of it

Bottle #2...

Could be a medicine, flavoring or any other kind of liquid used in small quantities, would have had a paper label identifying it, 1890-1920ish

Bottle #4 looks like a chemical bottle, maybe a photography chemical or something that had to be meted out in specific amounts.... I can't make out what the third bottles says exactly, looks like a soda....
