Is it covered in ink?
I think CHADNUM1 is right, looks like a picture frame tool.
Might be a jig to trim 4x4's when setting fence posts. Set the posts and then set the clamp and use a circular saw to trim the posts to correct hieght.
It looks like a type set frame from an old printing press.
Square picture frames less than 4" square???? I can’t envision it.
Hi there, this is my first post and I think I can shed some light on it, The clamp was use when drilling or otherwise cutting holes in the 4x4 ceramic tile.
