Hi, I found this today: "BALDWIN UNVEILS MODEL 248A PROFESSIONAL PIANO AT NAMM SHOW LOVELAND, OH. JANUARY 10, 1997 - Baldwin Piano & Organ Company is proud to introduce its new 248 Professional upright piano at the Winter 1997 NAMM show in Anaheim, Calif. Crafted in the U.S.A., the 248A model provides beautiful tonal quality, responsive action and exquisite cabinetry. >>The 48-inch tall piano features a unique Baldwin equal tension scale. In this design, string lengths are recalculated to make the tension equal throughout the middle and treble ranges. Increments in string tension at lower and higher extremes also follow a consistent pattern. >>This uniformity of tension results in more consistent tonal characteristics. In other words, uniform tone across the entire keyboard. The equal tension scale also enhances tuning stability.[...]" http://www.baldwinpiano.com/about/news/97_archive.htm#news_11 Clark
