Not sure it's the same company, but two of my first two bowling balls in 1990 and 1991 came from a Bowler's Supply Inc. They used to send a huge catalog in a red, white and blue three-ring binder to a lot of bowling alleys in the South. Their stuff was always good and you always got it quick, but that was in the days before the Internet.
I guess you just call them. Their local phone number shows it comes out of the Harrisburg, Pa., area.
