Set of 3 Vintage Bottles - History Unknown

These bottles came from the estate of an antique dealer.I have searched, but have not found out much about these bottles.
1-Small rounded shoulders bottle. One the bottom is the Owens-Illinois Glass Co. logo and a 12, 9 and 6. It is approximately 2 ⅛” tall and 1.75” wide. It would have had a twist cap.
2- 6” bottle with a bent long neck. No markings (and if you know what this bottle was used for, please let me know!). It would have had a twist cap.
3-Small rectangular shaped bottle with a 3 on the bottom. Approximately 2.75” tall and 1” wide.
No chips or cracks on any of the pieces. This bottle would have been corked.

Most items in my shop are vintage and are not brand new and come from estate sales. The items may show minor age-related wear and/or minor flaws consistent with the date of manufacture (please be sure to check photos carefully as they are part of the description). I do my best to describe any imperfections. If you have any questions please don't hesitate to ask!
