1939 Packard Front Wheel Bearing Nut Assy

Removed the left front drum today to do an inspection of the brake shoes.

I have never seen the way the front wheel bearing is held in place before on any vehicle. I am used to seeing the old "castle" nuts and a cotter pin.
This it had a cotter pin, an outer nut, a unique washer with numerous holes around its perimeter and then another nut that had a dowel pin that would engage a hole in the washer. There was a small piece of broken metal that I assumed engaged the keyway slot, otherwise there is nothing that would prevent then from backing off

Any idea what this is called and where I can find a set?
