Odd 2oz Ball jar anyone?

[Hestia]

I found this guy under my house. It’s an odd size and also has odd threading pattern on its lip. I know they can be dated by the different “Ball” logo styles, but it’s juuust a little too small to clearly see it.

Hestia, cool lil jar... The thread style can help identify age as well. I believe that is a quarter turn fast thread. If you find out when that was patented it will at least determine the jar's earliest possible date.
Good luck, ~Fred
