Lots of problems here! Greaves are also known as jambarts and as shynbalds. The cuisse is also known as a Cuissart. The 'elbow cop' has a proper name: a coudiere! The complete arm item is not called a vambrace. Only the lower forearm piece is called that. The upper triceps part is called a rerebrace, and the elbow part a coudiere. The poleyn is also a grandouilliere. And the coat of mail is called an hauberk or hauberque. And that's not a codpiece! Only on clothing is it called that: in armour it is a 'brayette'! I mean, that's how it is.
