Is this combination of Segmentata/Chainmail armour historical?

[Dan Howard]

A bunched cloak of some kind. A tube-and-yoke typology with a multi-piece shoulder flap. Regular segmentata with the torso detail painted rather than carved. Perhaps we finally have evidence of D'Amato's fabled leather segmentata

The fantasy illustration in the initial drawing doesn't actually look anything like that sculpture. It has been modified to look like the shoulder armour worn by Scottish border Reivers, which is certainly one interpretation but hardly the most likely one.
