Quoted from 1974DeltaQueen:My Flipper Pool #1 ball was replaced with an orange 5 ball ... so I'm carefully observing this thread for tips . Already paid the 30.60 to PBR so I'm all ears
Paint it yellow and be done with it. You can easily print out a small #1 with a circle around it and glue it onto the ball. No one will know the difference.
