Semi Rare Old Jet Black Roto Grip Roto Star 16 Lb bowling ball 🎳 bowling ball.

I clean and sanitize each ball before inspection after inspection I noticed the ball is in very good condition with very minor Nicks and scratches I found this ball to be semi rare with not many of the vintage ones left out there this is the only older one I ever found made by this company.

The finger holes are approximately 3/4" and 1-1/4" apart center to center, the thumb hole is approximately 1" and 5-1/4" from thumb hole to finger holes center to center.
