Help identifying and age
I have five of these glass jars. All five pieces have the same identifier on the bottom. From what I can find on the internet they might be Whitall Tatum. I tried to take the best picture of the glass as possible. The seem funs from top to bottom. The glass is clear.
I would just like to know the manufacturer, approx date produced and if these pieces are rare. Any help or guidance would be greatly appreciated.
