Cylinder Jug Barrel 5023005144 *CORE* 

This is a core cylinder. I vapor honed it to make sure there were no cracks or major damage but will need bored or re sleeved before use. I think its at the standard size now, but there is scoring on the walls and wear to the ports. Cannot be ran as is. Includes the power valve cover, but its just not in the first picture.
