I own a Hammond model B console organ from early 1936 when the company was still called the Hammond Clock Company. Unlike the BC of December 1936, mine has a tremulant vs, the vibrato scanner with the 3-position switch. When I bought the organ, it came with loose-leaf binder with the Service Technician Bulletins for the A, B, and E Concert model Consoles, and the various Hammond Tone Cabinets available at the time. Since getting that organ, I've done much research on Hammond Organ history and have contributed to the Hammond Organ pages.
