Determinations I can make so far:

The engine did NOT have a magnetic oil drain plug.

The piece that stopped the pump definitely can/could have made it through the pickup screen.

The piece that jammed the pump was probably stirred up by my adding the new oil.

The engine never even made one revolution when trying to start after the oil change. The pump jammed instantaniously.

The dents in the pump rotor I believe were from my slow cranking the motor over by hand. 2 dents in each rotor correlates with the 2 revolutions I cranked the motor by hand, looking for TDC #1.
If the motor had run with chunks going through the pump there would have been MUCH more damage.

SO, I can determine that my adding the new oil stirred that chunk of magnetic steel up and over one of the baffles in the pan. It was probably happily living in the pan for a long time in one of the "tubs" formed by the baffles in the pan.

There is still quite a bit of oil in those baffles. Oil that I need to inspect.
