Flutes with uniformly sized and spaced holes, such as flutes, support a fingering that is as natural as opening all the holes from bottom to top. Its not hard to imagine historics flutes being played this fashion, and all our efforts to create tuned scales with cross fingering and half-holing is a modern invention.
Since there is no evidence that historic flutes (uninfluenced by western scales) were tuned precisely, a historic flute that played this scale would be a matter of luck in where the finger holes were placed. Some have described historic flutes as visually tuned instead of auditorily tuned. But even though simple rules of thumb on flute dimensions and where to put finger holes were probably used, these rules were probably filtered by what worked, what didn't, and what gave a pleasant sound.
