From the front, this piece looks like an authentic Overhoff skull. It's hard to tell about the backside because of the quality of the photo and the amount of dirt and foreign material on the back, but the edges look alright and the prong attachment points (from what I can see) look fairly good... Based on the photos alone, I'd say there's a good chance that this is an original skull.
Thank you daveward. This skull was found one man on local forum. Also found two coins. I will try to get better photos.
You are writing M1/24 on the title and then you want to know which maker It is?
I think he was asking about authenticity, as opposed to identification.
M1/24 is Overhoff.
It looks fine to me.
