The Armour Archive

If anyone recognizes these terms, please see my post on the Armour Design and Construction forum. They appeared in 16th-century works quoted in Strickland and Hardy's The Great Warbow.

See my response on the initial thread. I believe a German jack is one most likely set up to be worn in conjunction with a breastplate, which has less layers where the breatplate lays, but otherwise is a normal jack.
