A custom ordered Churburg #13 breastplate. Nine sections articulated on leather. Polished 16ga mild steel with engraved brass edging and a flip-down arret (lance rest). New and unworn in combat, ready to rock and roll right out of the box. The central three plates are 13 1/2" at the center by 16" across measured just under the arret. Weight is 7 lb 2.0 oz.
