Second set of photos
Photo Apex Scrapes shows that the ejected apex seal
piece probably made it around the chamber a couple of times, one
impression looks to be smaller than the width of the ejected piece - so perhaps
it broke up further in its round.
Photo Apex Slot Peened shows that the 2nd apex seal
of #1 rotor that would not move up and down - clear why, now. The
departing piece peened over the slot and froze the seal in its slot. I had
to pry the opposite end of the seal up to the position you see.
