Dear fellow technician, I have an unused action frame for model B; Steinway part no: 9073. It is intact, the way that it came from Steinway factory, we just decided not to replace it. It has let-off screws and buttons on it, no sostenuto. I would gladly resale it to whom it maybe useful for $375.00! I cover the shipping. It's a great deal. As far as Steinway parts are concerned have you tried NY improved parts. I think they're great. Thanks George Golka, RPT 713-899-0280 jg@ruf.rice.edu
