The far east guys are johnny-come-latelies when it comes to manufacturing phenolic resin pool balls. They, however, have been very active, along with companies from around the world, including right here in the US, in the manufacture of polyresin balls. Only recently, and Garczar is on top of this, have the Chinese, Japanese, and Taiwanese been building phenolic resin balls, and they were brought into the business by Saluc. When your Raschig balls were built, there were only 5 companies capable of manufacturing phenolic resin balls in the whole world. Les Usines used to mimic some of ABB Co's designs. So did LaDecalite. Raschig built a copy of Brunswick's (ABB Co.) Royal Centennial, but they called a "tribute" ball. Few here know the relationship between CBB Co. and ABB Co. A large portion of "Hyatt" balls were actually manufactured by CBB Co. and shipped to Albany as blanks.
"iusedtoberich" purchased his balls new from a reliable source and in their original packaging. There is an ongoing undercurrent about pool ball forgeries and yet no one has ever come forward with a forged ball with unimpeachable provenance. I might be wrong, but I think it was Cyclop who was the first far east manufacturer of phenolic resin balls to come onto the scene, and that was, relatively speaking, just recently.
Furthermore, if Raschig was aware, as they would have been, of any attempts at forgeries of their world famous ball, they would have done something about it.
