I went way outside of my knowledge and comfort zone and picked this up with a little nudge from a fellow forum member from very limited pics I gave him. I could not find another exact example but did find an example of the lid. I am hoping to confirm that this is a period stein for service and not a post war pile of junk. Seems well constructed and the hinge looked like period examples. All thoughts and opinions are appreciated as I am way out of my wheelhouse.

I hope to have the translation of the bottom correct but the top I am having trouble.
