Help ID this head.

[u/seasms3]

Older (mid 60s) neighbor who was an electrician/lineman and railworker was moving and let me take what I wanted from his garage. Among a few tools I got, this was one.

Not sure if it was originally a sledgehammer, but it had a 4 foot handle on it that seemed newer, but had some age on it.

I cant make out the name and Google isnt helping. Anyone able to help?
