Here's what Steinway's site says (http://www.steinway.com/steinway/specs/model_o.shtml etc.): For the Model O: Braces 4 solid spruce; spruce provides tensile strength with less weight. Maple dowels fasten braces to rim producing a single homogenous foundation upon which is built the entire tonal component. A cast iron treble bell, affixed to rim's underside at treble bend, holds plate firmly in position by means of a steel bolt. The S & S iron wedge anchors brace ends securely to crossblock assuring permanent rim posture. For the Model L: Braces 3 solid spruce with a volume of 1,678 cu. in. (27,497cm3); Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim & crossblock producing a single homogenous foundation upon which is built the tonal component. Note: Treble bell is not required in smaller grands of lesser tensions. --Cy Shuster-- Rochester, MN ----- Original Message ----- From: BobDavis88@aol.com To: pianotech@ptg.org Sent: Friday, October 17, 2003 9:57 AM Subject: Re: Private post/Steinway Tone Bell Michael G asks: do you think the Tone Bell is only to be found in pianos with a Sos Ped? Did S&S rate such a piano more highly than one without? Can't answer that one, but the early NY A's had a sostenuto and no "tone bell", while the next version (1890's) had both. Do you take care of any recent (post 1900) A, B, C, or D without a tone bell? Bob Davis
