I was just reading the ad for the Marque Ampico upright and noticed
that the fellow described having installed a full set of crescendos in the
piano. I have a foot-pump Marshall & Wendell Marque Ampico and have always
thought the system was complete (minus the modifying levers on electric
versions). Is my piano missing part of the expression unit?  Thank for any
help on these matters.
