Stephen, If you don't get what you need on the Bluethner, send me an e-mail. I believe I have a Bluethner manual that covers that action. Also I can give you names of several technicians in Europe that know them well. I am sure that Bill Kasimov (long-time Bluethner dealer in Los Angeles 9tel. 213 466-7707) would be glad to help you.
