The original blue colored one. Would like to find this ball drilled either Righty or Lefty, doesn't matter. And either 15lb or 16lb, doesn't matter. Needs to be in good shape and NEVER been resurfaced.
If the thumb or fingers have been plugged and then just the thumb plug or finger plug ONLY has been sanded down to smoothen it out, and not the WHOLE ball been sanded down... then that's fine!
