Ric, Regarding the wood which was used for the bridge, it probably isn't maple, but Sycamore. Both are from the family Acer, but one is sacharum (rock maple) with an ADD of 7.0 to 7.2 gr/cc, while the other is Acer pseudoplatanus, with an ADD of around 6.0 gr/ cc. Bösendorfer used to use pseudoplatanus for their bridges, and it was inclined to allow the bridge pins to stand up. They both look the same but the rock maple is the real McCoy. Samual Wolfenden wrote about maple being weaker than Beech. He was referring to psuedoplatanus when he was writing about maple. He knew.
