Andrew, thanks! The volume I have has CPE Bach, Nichelmann, D Scarlatti, Froberger, and JS Bach. Maybe your volume got uploaded to the IMSLP with a different number.
My wife & me have a Schimmel upright piano which certainly has too big a sound for the room it's in. [One neighbour complains sometimes.] Well, in a decade or three, when we're finally rich, maybe we'll move to a place where there'll be no neighbours to bother with XVIIIth century music
