    The title of this listing is very misleading. The key was used by a watchman as part of a watchclock system. A watchclock allows the patrolman to insert their key to punch a paper with their key's "unique signature". In England, they were also used to ensure train schedules were followed by marking when the engineers departed each station.

    Default High Security Adjustable Bit Prison Guard Door Lock Key

    I knew there was no way it'd be used as a prison guard key. That's why I was waiting to see if someone would come up with an answer. So the collection made a mistake of what it's really supposed to be. Thanks for the heads up .....Timothy....
