I'm guessing this 426AD3-4 somehow managed to slip past the heat treatment. It was bucked no more than the others and even the manufactured head got squashed!
The 3rd photo is after pushing in a centrepunch by hand.
If you got a bunch of these and set them with a pneumatic squeezer, you might not even notice, except for the squashed manufactured head.
