I have a complete, unrestored early Ampico A action (floppy pushrods,
cast escutcheons) out of a 5'4" Knabe baby grand.  As an act of youthful
enthusiasm while in high school in about 1964, I built a walnut
cabinet, a 'keyboard', and arranged the action with drawer over stack
over expression components and ended up with an Ampico Vorsetzer.  This
was not a roaring success; my ex has the cabinet and I've stored all
the pieces since then.  Nothing has been damaged by my efforts (not to
mention mice).  Offer a modest sum and come get it in Philadelphia.
