Just a little FYI: Flyback cores are assembled with deliberate gaps. These gaps are critical to the magnetic properties of the flyback. The idea is to get the proper inductance without having the core saturate magnetically at peak current. In older sets, the gaps were sized by thin hard paper between the core pieces. In later sets, a dab of glue containing microscopic glass beads was used instead. This made the gapping more stable, but meant that the flyback could not be disassembled to replace parts of it. This is almost surely what you have in this set. The random gap due to breakage ruins the magnetic properties of the core and even if there weren't tiny pieces missing, there is no way to take it apart and put it together again with a tight enough fit to eliminate the extra gap.
