If you are inspecting a Miyazawa flute, use this quick mental checklist:
: On some models, the number is stamped on the ribbing underneath the trill keys. Miyazawa Serial Numbers

The recurrence ( a_n = a_n-1 + a_n-3 ) yields: [ 1, 2, 3, 4, 6, 9, 13, 19, 28, 41, 60, 88, 129, 189, 277, 406, 595, 872, \dots ] This sequence grows with ratio tending to the real root of ( x^3 = x^2 + 1 ), approximately ( \psi \approx 1.465571 ). We denote this the Miyazawa coefficient .
If you are buying a used Miyazawa, to ensure the instrument is not stolen and to know the accurate model year. Because Miyazawa treats every instrument as a custom

Production numbers are lower, and the numbering system has transitioned through distinct structural eras. The Early Era (1970s – 1980s)
