It's a urethane ball made by Columbia 300 (they labeled them "Bonanza", I believe for use as house balls) that comes in blue, black, and that color there.
Champ's right to say that its only use would be as a spare ball. It could conceivably be used on broken down dry lanes. However, keep in mind two things:
1 - while reactive balls are urethane, they also have additional features that enhance their skid and also enhance their grab on dthe dry. Plain old urethane doesn't skid as much, and doesn't hook as much. So your use on dry lanes has to take into account that the ball will have a net very slight arc towards the pocket as compared to a plastic. That might sound like it's a winner, until you see point number 2:
2 - It's very old, so the core is not modern.
All things considered, drilling it is a waste of money, IMHO.
