Accu-just HPs in Steinway D :(

[Robert Hohf]

I can't visualize how the Steinway has been retrofitted with a Mason &
Hamlin resonator.  In M&Hs the resonator is installed above the braces and
below the soundboard.  The pianos are designed with space there for the
system.  The resonators are installed in the inner rim before the outer rim
is attached.  In a S&S the soundboard would have to be removed to have
access above the braces, but there isn't enough space there anyway unless
the braces are notched (and their integrity compromised) to accommodate the
legs of the resonator.  In the S&S how are the legs of the resonator
anchored to the rim?
