Notes:
This breastplate appears to be of Duplex construction.
Duplex breastplates are formed from two relatively thin sheets of wrought iron, kept separate but forged together into intimate contact over their whole extent. In many, the outer layer has flanges folded over the edges of the inner layer; in others the two layers are either riveted or hammer welded together. The intention was to create shot-proof armour without appreciable weight penalty.
