Herb Lindahl here, from central Connecticut.  I have a complete
(and I do mean 'complete') full Duo-Art mechanism from a Stroud
(Aeolian) grand piano circa late 'twenties, or early 'thirties.
It is the type that routes the tubing around the keys as opposed
to through them.

The stack scale is as follows:  24 bass, 30 middle, 26 treble
(80-note stack).  All control levers are above keys in spoolbox area.
Very good original condition.  No prior restoration, untouched,
clean, no rust; I have tear-down photos to show how they were
arranged in piano.

Asking $500.00.  Will pack and ship, or possible delivery within
100-mile radius for reasonable cost, if I am going that way, or
pickup here in Connecticut.  Email with any questions.  Thank you.
