Thanks for all of the responses on this. I am attaching a picture of the bottom.

From the US and this vise is a Michigan barn find

This group has been a great resource for me to identify and learn about the many vintage vises that I am seeing this year. This one has me stumped and any info is appreciated. It is old, heavy, and unmarked. It has a 3" Jaw and is in great working condition. It was bolted to an old table that was purchased for $5.
