Do we need to keep different collections of the same instrument?

As shown in the screenshot, we have four instruments called “whistle”, they have different QIDs, in fact they are four collections. I wonder if UMIL is more concerned with the types of instruments or the specific collections. If we are more concerned with different types, maybe we should delete some entries about specific collections.
