Yes it is interesting how things get abandoned and lost probably for the
sake of manufacturing expediency.  These types of bridges are clearly more
trouble to make but probably with some real benefit.  Here's a couple final
pictures.  The treble backscale is quite long without the tuned rear duplex
aliquots and you can better see the angle in the capo section.  I'd probably
reduce the felt width and density behind the counterbearing bars to reduce
drag there.  Anyway, a potential project in the making.  We'll see what
happens.  A piano where the value doesn't really justify the cost of redoing
it but it may have the inherent design and structure to be quite a nice
small piano (good set of ivory on it too!).  A family heirloom so there's a
chance.

Very good! No tuned low angle duplex either. Can't tell how steep the 
angle is or how much pressure and drag the big felt acreage provides.

Surely.

It's terrific how much individuals have learned and implemented through 
the history of this industry, and sad how very little of the good stuff 
has survived in current production and general knowledge. But that's not 
just this industry either, is it.

Good find.
