Latten

Brass, Bronze or a mixture of the two. Generally a copper base metal with elements of tin or zinc plus other trace elements. During the 14th century latten might well have been used for select armour bits, such as knuckle gatlings , couters , poleyns , and for trim on armour during the latter part of the century. This trim might be further enhanced by engraving (especially Latin phrases from the bible or local mottoes) or by punchwork designed to emulate rivet heads.
