As I recall, it used a wire brushes only, ideal for the rubber balls of the era. In production for many years up until Brunswick replaced it with the Lustre King I believe. The Lustre King differed by using a dense cloth buffing wheel and utilized a compound block for a polishing agent. Also an excellent machine if properly maintained.
Thanks for sharing this :)
We used to joke that repeated use of these wire-brush machines gradually made your bowling ball smaller. That’s how we kidded a guy the first time he put the ball through the baby split (3-10) without hitting either pin. Of course, that kind of thing happens regularly today.
We have one of these in our bowling alley, functions great. We too are having problems finding any parts for it, so we use it sparingly. If anyone on here knows of any place could you let me know as well?
