I have a similar bottle but my numbers in the middle are 2090 6
I have one just like yours. Mine has an 8 and a U on the bottom (in the middle). It belonged to my Mom. She had several. She often canned home grown, home canned applesauce in them. So the jar has lots of nostalgia value for me. I have a vague recollection that she called them "coffee jars," but I don't find anything like them used as coffee jars online, so maybe that memory is rusty.
Thank you for the patent info, Chris. I was glad to see the dates. I've often wondered about the jar, and thought it looked kind of Art Deco. I guess that was appropriate.
Here's a history of the company, complete with an illustration of "our" jar.
