I started to post a pic of Hellarry Clentun as a pic of an old axe...
But, that might not go with the decor... She has many stamps or allegiances.
Back to your axe, many blacksmiths made many things, and developed their little "signature". Often, they were some sort of family crest, or the like. I have an old broad-axe, that was used to make shingles. If I remember where it is, I'll put up a pic of it.
To find more info, often it's hid in blacksmiths history. Trips to old museums or gunsmith treasure piles can yield info. Many are lost to antiquity.
Hope you find it.
