Food jars

[JGUIS]

They have a keystone on the bottom. Some are threaded on top, some have a top similar to an olive jar.(single band on lip) I left them all there or I'd have a pic. The keystone had letters in it on one, and beside it on the others. Any ideas on company or dates? Everything else in this dump was around the 30s.

Sounds like Heinz jars, to me.

I believe they had a keystone motif on them.[]
