Early Duo-Art Theme Box and Tracking Device
By Barry Dennis

Sam Harris invited me to look at the photos of his Stroud Duo-Art
upright concerning my inquiry about the early Steinway grand Theme box
which apparently contained tracker pneumatic valves.  I viewed those
photos and want to thank Sam for responding to my inquiry.

While the configuration of the upright Stroud stack, which contains
what look like two theme valve boxes, is not similar to the elongated
theme valve box in the early grand spool box, it might be that the
second valve box in the upright Stroud contains two tracker pneumatic
valves which could be similar to the tracker pneumatic valves in the
early Steinway grand spool box assembly.

Does anybody else have any thoughts about this?
