A friend experienced exactly the same problem on a 1941 180, it backfired so bad it blew the seam on the air filter. On a second occasion it blew some of the exhaust system off the car.

Problem was so simple, the shank of the plastic distributor rotor had cracked and the rotor was able to move independently of the distributor shaft. And it was a new NAPA (Echlin) rotor!

EDIT: But now seeing what happened to your distributor, I'd say that is indeed an extremely rare failure mode; I've rebuilt dozens and dozens, perhaps hundreds of distributors and never seen that!
