Ax head Identification

[Brian Rust]

Got this today at one of my usual stops. At first I thought it was a 5 or a 2 after a very light clean up it is definitely an S. Has anyone ever seen this marking before? There are no other markings to speak of, thanks for the help!!

Paper label axe.
I've seen a few axes before with an S on them like this but I don't recall if they got identified or not.

That’s what I assumed. Hopefully someone will have an example.

Plumb?

First thing that came to my mind. Seems I have a Plumb with a five stamped on the cheek. I will take a closer look.

The general shape looks Kelly to me.

I'll add I have a Kelly with a P stamped on it that that looks very similar in font, size, and location.

I thought kelly when I saw the shape also. But I know Plumb made a lot of paper labels with weird stamps. So idk. I figured if it was kelly there would be eye ridges but it does Not.
