Your picture in post 87 shows an X02 package all right. However with an LO3 leadout the collector should have a bigger gap between it and the base than there is between the emitter and the base. It's difficult to tell from your picture, but it appears that the bigger gap is adjacent to the black lead which would make that the collector. Can you confirm which is the bigger gap please.

Yes indeed - small though they are, there is a wider gap between the red insulated lead and base than black, red being the lead against which there is a dob of white paint on the metal cylinder. I've bent the leads away for a better view: (sorry, focus not quite the ticket)
