I found one very much like this last year at a garage sale and purchased it.
Pritzlaff was a Milwaukee, Wisconsin Hardware store. I was told that National made them (as someone else posted above.) Mine was in Turtle Lake, Wisconsin for much of it's life. In one of the drawers was a 1910 silver napkin ring. I'll need to post some of my photos. I need to do some digging around for the serial number.
