Howdy All,  In regards to John Tuttle's post, I am sure this is an
Artecho system.  Three years ago I converted a grand with this system
to an Ampico A.  I still have some of the expression devices and they
look like the ones in his pictures.  There was an Artecho decal on the
fall board.  Also, since Artecho was also made by the American Piano
Company, there are a few Ampico parts mixed in there.
