Ships From Hawaii Ebay Shipping Times Do Not Apply USPS Ground Advantage 7-14 Days Not Guaranteed, May Take 30 Days EBONITE Measured Specs: 16 lb 1 oz, TW 3 1985 - MAGNUM 10 5N2N076 I think the MAGNUM 10 was the last produced ball of the MAGNUM series, last appearing in the 1989 Ebonite Price List. 1990 - No Magnum Bowling Balls 1989 - Magnum 10 1988 - Magnum 12, Magnum 10, Magnum 5 Gosh, those were the days. I even visited the dirty, dusty Ebonite Hopkinsville plant with the rubber smell that was so familiar as back in those days many companies were openly retreadingautomobile and truck tires with the rubber smell in the open air.Well, maybe good that OSHA was created, not sure if they played a part in the demise of rubber bowling balls but from a safety stand point the Ebonite workers were happy.Think also the BRUNSWICK BLACK BEAUTY rubber bowling ended in 1989, graphic label changewith BLACK BEAUTY plastic bowling ball also having 1989 serial numbers.
