Armourer
Historically, an armourer is a person who makes personal armour, especially plate armour. In modern terms, an armourer is a member of a military or police force who works in an armoury and maintains and repairs small arms and weapons systems, with some duties resembling those of a civilian gunsmith.
With the renewed interest in traditional armour and weaponry, the occupation also involves working with film, stage, and historical and reenactment societies. Period costumes may require reproduction armour, swords, and related equipment.
