Del Fandrich has taught about improved tone with longer back scale length in the lo-bass and I believe him. His portable device demonstrates this for all to hear. If you get a chance to take this class you should. The lo-bass on this piano especially had short back scale and the extra 16mm helped get the back scale length closer to 80 or 90mm on the lowest few notes - excluding the tied part of the wire - cannot recall exact lengths. I would have shortened the lo-bass speaking lengths more but was restricted by the plate casting. The original bridge and its cantilever was also replaced with a new bridge and no cantilever.

Looks like you put the long bridge back in the same relative position to the plate, but shortened up the speaking lengths in the bass by 12 to 16 mm. I would be very interested in knowing what led you to make this change?
