Hello Joseph, The factory has asked me to respond to your inquiry. As odd as it must seem, "there is no record left so it is impossible to find out how many these synths were made". Sorry for the death of information. Well there is the answer we will never know. Makes owning any Kawai Tesico Synth all the more lucky .
