My question is whether it could be a time-honored copy of part of an armor of the type OSHITSUNE-GOTE DO-MARU ARMOR.
A full armor was sold at Christies EDO PERIOD (17TH-18TH CENTURY) The Japanese Aesthetic Christies London, South Kensington | November 7, 2012. GBP 103,250

These kote have some rust on parts of the arm's chain but when can they be made?
