  3. AI is directing you to W. W. Kimball Company but it looks like A. Kimball Co. is unrelated.

  4. I tried to negotiate that misinformation (AI doesn’t seem to do history very well- or I’m not smart enough) But I think A Kimball was also a piano manufacturer.

  7. With piano sales at an all time high, and woodwinds humming along close behind, Mr Kimball then called for a major expansion in the percussion department, hoping for sales to explode there as well.
