You mean an AMERICAN SHUFFLEBOARD brand? If so, they have changed hands several times over the past few years. They used to be in Paterson Plank, New Jersey for many many years, but they've moved so much lately I don't know where they are now.
I think their last name change was Venture Entertainment Products Company at phone number 1-800-461-2525 or fax (732) 914-9166. They did make an electronic scorehead retrofit kit for the old electromechanical models.
BTW, many American Legion, VFW, Eagles lodges, taverns, etc in my area still are operating these old electromechanical shuffleboards even though many of these tables are 40+ years old. Just keep the stepper units cleaned, adjusted, and properly lubed and they'll run and run. Naturally you'll need several boxes for of #47 miniature lamps for these babies.
