Antique Vintage selling Half Hatchet Head (1960s)

ONE OF A KIND Vintage Axe Head. Shingle/Roofing Half Hatchet Pattern. Estimated to be from the 1960s.

Overall Length: 7&3/8th inches.
Edge Length: 2.5 inches.
Just over an inch wide.
Weighs: Roughly 2 lbs.

Condition is how you see it in the photos.
The axe is polished and selling shiny but also has vintage wear, some scuffs and scratches. Very very minor chips off the cutting edge. It's old and well used. See markings in the last photos. Based on positioning and crudeness, this is very likely the original forger/smith's initials as it has not been traced back to a company name or logo.
This makes this axe head a VERY RARE find.
