I purchased this ball from the estate of an avid collector of bowling balls and do not have history about it beyond that this ball was purchased several years ago and stored. This was stored in a bowling room within the climate controlled house. Please note that I did remove this from the plastic to inspect and photograph and noticed the following: 1. Ball (at least on my scale which may not be completely accurate as it is not a bowling scale) weighs closer to 15 13 oz (see photo). 2. There is a CG hole and Mass Bias mark as photographed. 3. The USBC label was removed and filled as photographed and mentioned on the box. There is also some light surface scratching. 4. This was banned by the USBC in 2016 after determining that the balls didn't comply with specifications and requirements outlined in their manual. Unapproved balls may not be used in USBC certified competitions. Please keep this in mind when bidding. 5. The box has some tears/damage and is written on. Please let me know if you would like to see additional photos. Please understand that although this ball has not been drilled, it is a discontinued/banned ball (back in 2016). I am happy to answer any questions that I can. Overall, a rare find! I am not sure I have seen an original Jackal undrilled in many years. It is a powerhouse!
