The Music House Museum, in Northwest Michigan near Traverse
City, has recently reorganized its workshop storage areas and has
multiple complete or duplicate parts from Duo-Art, Ampico A, and
Welte "Red" T-100 reproducing mechanisms.  These parts are available
for a reasonable sale price in order to clear up storage space.

Source pianos for most of these are long since gone.  If you have
a particular need please contact
