Geoff Ward asked, "Is the Marque Ampico inferior in any way (apart from
lack of a motor) to the ordinary powered model A Ampico? Is an upright
Ampico inferior to a grand Ampico?"

Good questions, but difficult answers!  The foot pumped model depends
on the talents of the pumper to provide appropriate accompaniment
levels, just as a regular player depends on the talents of the pumper
(given that the player and piano are in good condition) to provide a
"live" performance.

Upright vs. grand; two different animals.  A well-regulated upright will
do better than a poorly regulated grand.  And then you can get in the
"Chevy vs. Ford" kind of arguments, too!
