A golf ball without dimples is, well, a heavy ping pong ball. This early-20th century diecast machine patented in 1915 (EX-MT) gouged the mini-craters that make the ball fly straight, far and true -- if you hit it right. "The Rolling Die Does It" says the engraving of the Fulname Co. in Cincinnati on the base. The metal device weighs about 10 pounds, 10.5" from knob to base and 6.5" wide. Comes with an ancient looking ball which is held in the things vice-like clutches. A pendulum device swings over it, puncturing its surface until the ball is covered with dimples. .
