Hi Jack,You've jarred some long sleeping memory cells! Way back when I was "thinking about" a career in piano technology(1974-75?), my next door neighbors left their Ahlstrom upright piano in front of their apartment building (sans top front panel). After confirming it was "free for the taking", I gathered a few friends to haul it up several steps into my apartment. I had it for about 5 years, and moved it several times as I moved around University Circle (Cleveland). When I "got serious", and attended Robert Perkins' piano technology school on the west side of Cleveland, I spent many hours at it, toiling away at the basics. Philistine that I was at the time, my frustration with "interference" from the auxiliary strings singing away in the high treble, led me to remove those strings. I passed it on to some friends when I moved back East (1979). Patrick Draine On Sat, Jan 31, 2009 at 1:23 PM, <JWyatt1492 at aol.com> wrote: > Hello to all, > > C. A.
