I have made reference to J. Bauer pianos in several of my Journal articles.
They did not have double soundboards, they had ribs on each side of a single
soundboard. These ribs were each about 1/3 'normal' height and paralleled
each other. In other words, the rib on top of the soundboard was exactly in
line with the rib on the bottom of the soundboard. Excellent thinking on the
part of old Julius. And not at all like a double soundboard.
