Roloff Manufacturing Corporation is a family-owned, gray iron foundry, currently celebrating 80 years in business. 

I tried to find more information on this maul head.  I don't know if it was used for pounding posts or a railroad hammer.  Either way, it is very heavy for its size, weighing 15.6 lbs., and measuring approximately 5" x 4.5" x 4".  

It did have a splinter of a handle on it, which I did remove.  

Please examine all pictures carefully, since I do not accept returns.
