Fishes instead of eyebrows on helmets?

[Peroni]

Does anyone have a good image of this other figure that might represent the LEGXIIII soldier? Given that the tombstone of Gnaeus Musius is usually used as evidence of the LEGXIIII shield design, it'd be interesting to know if the Mainz pedestal representation supports that...

Here's the soldier leading the captive.. It also looks like he's wearing his sword on the left!? The pommel, grip and guard are all clearly visible near the edge of the scutum.
