Hello, All. I pulled this out of the hammer bin, wondering if anyone else has seen one of these. Patented on one side of the head, looks like Lapeer Mich , and a company name on the other side. Brass faces look to be removable, steel? malleable iron? head. Width across head with inserts is approx. 4-3/4", brass faces are 1-3/16" dia. Thannks, Lou
