1907 Bechstein model D #83901
This 1907 Bechstein has an interesting feature illustrated in the 7th and 8th pic. In the right half of pic 7, as in all conventional pianos, the three bridge pins of each unison are oriented in a line exactly perpendicular to the stings. In contrast in left half of pic 7, the three bridge pins of each unison are oriented in a line not exactly perpendicular to the strings. This pattern is followed in the entire middle section of the treble bridge resulting in slightly different string length in each unison. This unusual arrangement produces supple harmonic beating between these uneven string neighbors, which is perceived as an increase in tone color, somewhat similar in effect to the vibrato of string instruments. Steinway also adopted this feature but both firms abandoned it later, possibly in pursuit of an ever 'cleaner' tone. Pic 8 is from a nicely done youtube video in the former Bechstein hall in London about the restoration and testing of an 1899 Bechstein E with the same feature.
As can be seen in several of the other pics, the restoration of our model D will need its original gate leg brass casters back. Originals from another piano are shown in the last pic. If you know where to get these, please let me know!
