I have a casting that looks like it could be a grenade body. Has anyone seen one of these before? It was bare cast iron and rusty when I got it, so I brushed it down and gave it a flat black paint finnish. It is marked S in a circle and 41 near the small hole, on the bottom? It is also marked 15 in the large hole. It has latitudinal rings on the inside and longitudinal grooves on the outside. Any help would be greatly appreciated.
