Ox-Head Brand axe head

I found this axe head at a local antique market in a box with some other abused tools. Although the back of the head has been all peened over, the cutting edge was pretty good. I bought it for a few dollars and when I started to clean it up discovered the Ox Head brand name. So it appears I've got myself the beginning of a nice quality 1 3/4 lb German hatchet!
