3rd Century AD portrayal

[Crispvs]

As an aside, does anyone know how you would (a) do the shoulders on a locked scale armour and, (b) given that locked scale is less flexible than some other armours how would you go about making a suitable opening to allow it to be donned and how would that opening be closed? The small locking breast plates found in late second century and third century contexts would probably be fine for a third century locked scale armour but what abut the mid fourth century?
