My Breastplate is an almost-identical copy of the one in Schloss Churburg armoury. Significative differences are in size for my own adjustment and the lance-rest (absent in the artifact) which I added for reconstructive-educative purposes. Breastplate, Ruestkammer Schloss Churburg, Schluderns 1390 ref_arm_3810
