I recently repaired this model of kyoritsu which one of my student brought. That has same inside structure to Hohner 32, or Stagg-32key ones (the position of screw is also same), so they share similar tendency in their sound characters. I guess that is a copy of Horner’s if it is not original? although the quality of reeds looks better than them — it was rust proofed. Actually the kyoritsu is not so commonly used maker in Japan, but still good instrument considering the price as Alan mentioned.
