Vivian Villarreals pool coach was the distributor of these great racks. His was called 'Duffy'.
I believe he had them made by a wood shop in San Antonio, and they were a bit pricey for the market at the time. He carried them all over the country trying to sell enough to go into production.
But, there just wasn't enough demand to justify the costs of producing the racks and a great product never made it to market.
