I see an old black rubber Tornado at work every Monday night.  This ball is drilled label, as was almost every ball back then, and I've noticed two small 5 pointed stars on the ball.  They are about 1/4" across and are located roughly 6 3/4" to the left and right of the grip center line.  

Are these factory markings and what were there significance?

It's kind of hard to read the lanes if you don't know their language...

Maybe no one old enough to remember this ball has a computer?

Thanks Michelle, my first ball was a blue Regency 300.  I went from 12 to 16 lbs. and ended backing up to 15 when I got a freebie at work.  

So no one knows what those starts were there for?
