The number 56444 (noted on 55828 as being for the sword) appears on the black
plastic piece (electronic casing?), and is the same inside all six weapons. If
I were to guess, the numbers for the main part is behind the electronics, but
I'm not quite willing to tear these apart.
Also when displayed like this it's apparent that 55825c01 has a naming inconsistency,
listing the set number. Is there a preference there?
