Unusual Holmes Holmes HABF-20 Box Fan from the Early 2000s

This is a rather odd Holmes box fan from the early 2000s. I suspect it is model HABF-20. It is very similar to the 90s model that I remember seeing in the middle school classroom, but it has the newer blade set that's still being used by Holmes to this day.

This cheesy, flimsy blade is paired with the older McMillan motor. Despite the blade being so thin and lightweight, it still has a nice slow low speed and decent variance in the speeds. It puts out quite a decent amount of air on high, if this were one of the braced-blades, I suspect it would put out even more.

I initially thought this configuration may be the result of Holmes trying to use up old parts before switching to the next design it came out with, but the motor appears to be a completely different shaft size than the older one. The blades are not interchangeable on this one. I suspect on the older one the blades would be interchangeable, as the issue on this one is a lack of depth on the shaft. The cabinets appear to be the same thickness.
