This is the side view.
And I am looking forward to learning to use it. The top seems pretty hard a 1 inch ball bearing bounced 9 inches from a 10 inch drop.
Picked this up at a yardsale in northwest GA for 20 bucks weighs 100.8 lbs all markings are worn off except a square on the side but can't make anything out in it. The body seems like cast iron with a steel plate on top.
