As you mention, some pianos using individual rests, such as some of the early Baldwins and a couple of others whose manufacture escapes me, are not movable. (The Baldwin index pin you can see if you look carefully.) Others, such as the venerated Steinway, are movable only in sections. Still others are cast into the plate. The front duplex arrangements are some similar. Early Steinway front bearing bars were, shall we say, semi-adjustable in sections. Later they were, and still are, cast into the plate. Others, such as the M&H, are easily adjustable both front and back. One recent piano using a so-called tuned duplex--Schimmel?--has individual rests carefully et into a milled groove, or slot, in a brass plate. Pretty, but hardly adjustable. Del
