That and the very shallow string deflection angle across the V-bar. I did a lot of prep work on these during the 70’s and became quite familiar with them. I remember one run of 45” pianos with such a shallow string deflection angle that I could easily lift the strings off of the V-bar with a stringing hook. The original designers tried to get some of the effect of the “tuned aliquot” string termination system in these pianos, especially so in the 45”—it shows up in the Model K as well—but it obviously doesn’t work very well. Both the 40” and the 45” pianos could have been quite good pianos with just a bit of redesign—actually, in the case of the 45” piano, that is still true. A better string termination system, an improved stringing scale and a new rib scale with relocated soundboard cut-off bars makes a world of difference in this piano. —ddf
