The brown between the ferrite core and the white coil housing is normal glue used in the flyback manufacture.
However, the rust on the metal clip holding the ferrite core together is definitely unusual - I've never seen this before. Obviously a sign of moisture at some point in its history. Is there any other signs of moisture? The clip itself is purely mechanical (holding the two parts of the ferrite core together) and serves no electrical purpose. As long as it's still structurally sound, it's probably ok.
