Help dating round Canada Dry bottle

Hello. I am new here and I am hoping someone can tell me a little history about this bottle. Not sure if it’s post or pre 1900 though. My Dad gave it to me and he got it in a yard sale. I can’t seem to find one like it just searching the internet. It has a thin long neck and it’s kind of slightly bent. The letters and numbers on the bottom rest G-2909. And it says Canada Dry at the base of the neck. Any info would be greatly appreciated

Looks like it was a 1970' s bottle.

Wow that's an odd thing. I agree on the date range, probably 60s or 70s. It was originally just a normal Canada Dry bottle, this is either someone's glassblowing project or a carnival prize. It's common to find bottles from that era with their necks stretched way out, but I've never seen one blown up like a balloon the way yours is before.
