Are these bottles old?

Fishsticks

Hi I found these in a Goodwill. They looked like they might be older but they're pretty heavy so I suspect them to be newer. Either way they would be good for holding flowers on the window ledge.

I also noticed the diameter of the opening is different for each bottle.

Thanks for posting.
I believe these are very late 19th century bottles - hard to say exactly what they were used for.
