The little Faventia barrel pianos are fun to work on, and they have
a nice bright tone.  The barrels are interchangeable; occasionally
you can see one for sale.

They always seem to sell for around $650-$740 in decent condition, with
the cart.  (These could be had with wooden carts and stuffed donkeys as
extras).  Without the cart, I would value it at around $450.
