Corazzina, type 2 on Red Leather
Usually, brigantine was made of small plates. However, small plates were kept impact badly, and since the small-plate brigantine supplanted usual, the plates were again enlarged, making the former bigger, but better fitting to body. A characteristic feature of a big-plate brigantine, in addition to large plates, was a skirt of laminar structures, that was absent in small-plated Brigantine. In later versions such a brigantine is in fact a cuirass, but covered with cloth.
The plates of this corazzina are made of cold rolled steel with a thickness of 1.5 mm. Base – durable leather. Plates could be made from tempered (spring) steel. Notice that color of leather could be a little different from what you see on this photos.
Please notice, that measurements should be with padding/gambeson.
