Do you think the Bow of the Winds from Ebou Dar cache is actually one See Folk used to own or another survived copy?
But I feel like the odds of it being the exact same device are pretty good. We know that there were many BoTW during the AoL, but we rarely see multiple objects that do the same thing survive the Breaking. IIRC (aside from a'dam which are different circumstances) we only ever see multiples of the Red Doorframes and the two Binders/Oath Rods in the series.
