CAPTAIN HOOK'S MISSING HAND

A question that has long puzzled me is why, in Disney-related adaptations of Peter Pan, Captain Hook's left hand is shown as the missing one, replaced by a hook.  The play states quite clearly that the crocodile bit off his right hand.  Not alone in the Disney cartoon but in the series Once Upon a Time, Hook is shown having his left hand missing.  Maybe cartoon art found a missing left hand easier to deal with in making combat scenes.  I daresay this must remain an enigma.

Hook with correct hand missing

Could the photograph below give some clue to the change of hands? Here we have Boris Karloff, who played Hook on the New York stage, with a hook on the left hand.

However, the change of hands remains a mystery.  Perhaps someone out there knows the answer.
