From the APTA Annual Minutes:
“Robert Frothingham reported on efforts with Barr Rubber Company to improve the ball and asked Stan Greene of Marcraft to report on their efforts to enter this activity. Mr. Greene stated that they have a source for balls but are still working on the flocking problem. They hope to have limited quantities available this season.”
