I totally agree with your assessment; and think that this practice has to 
do with a basic misunderstanding of what the front duplex is supposed to do.

The patent drawings help support this assumption.  I do not remember the 
patent descriptions sufficiently well to know if they confirm or refute 
what might be construed from the pictures as being a reinforcing 
system.  This is further complicated, I think, by the presence of the 
movable cast front duplexes still seen on so many older S&S pianos.

I'm sure that there are others on the list who are much more current with 
this stuff than myself...maybe they'll speak up.

Best.

Horace

P.S. - Almost forgot, I've heard some very good compliments about an 
instrument of yours that a friend of mine heard in Syndey...Opera House, 
maybe?  Good Show!!!
