long before my 1st shell, late 80's, little antique shop in waynesville oh had 3 weird large cannon balls with 3 fuses sitting outside in the grass. not knowing anything and cannon balls should only have 1 fuse, and pre internet, took awhile to find out they were real . beside, they looked really heavy, and the car was a long way away. 2 hr drive to get there, so took a month to get back and I hurried to the store. well they were gone.looking back, at $40 each, wish I had bought one anyway, but it was alot of money then for a guy starting a family
