Sounds like a T-bolt 1000T starving for power to me.

That sounds like a siren used to signal the end of the world.

Fascinating harmonics at that low RPM setting.
I would not even recognize it as a siren unless I heard the speed up and down.
As a young child, that would be scary sounding to me.

wasted brushes in the motor and/or collector rings, most likely.

I bet the collector rings because it is periodic change as though the collector brushes are passing over an oxidized or dirty area of the rings.
