What is this ?

Does anyone know what this hammer thing is ,please ? I found it  while mowing my place . It was sunbaking under a tree where the rains had washed the dirt off it.
It is made of  heavy iron and there are ID marks on the hammer end, the round handle and also right on the end of the round base but it is too rusty to read.  It is about 10 inches long  and appears to be from machinery.  

Thanks.

I don't have a clue SOF, the hole in the end is part of the machining process from the lathe.
All I can suggest is; it's a type of home made tack hammer, ?made as an apprentice exercise or tech school project???????????????????
It may have had a wooden handle?

Thanks, Moredeep. I live on a very old pastoral lease surrounded by historic mines and thought it could possibly be from either farm or mining machinery.

That my friend is the rock hammer that Andy used to escape in the Shawshank Redemption.Actually haven't got a clue looks like a homemade job.

It does look like a hybrid of some type.

I think it might be a railway wheeltapper's hammer.

Thanks Hiluxer. You might have it right there. I have never heard that term before and now i look it up there is a museum with wheeltapper hammers and even a very long song dedicated to them.and a wheeltapper's guild to boot !!! You learn something every day.
I found similar hammers online , but not he same one, but very close to what i have.
The nearest railway station was about 3 miles from me ,but closed down 70 or 80 years ago. Good detective work Hiluxer.

Wow you learn something new every day,well done Hiluxer
