Imperial Gallic A Helmet

[Primvs Pavlvs]

The Gallic A is dated as early as 25BC or so, making it 100 years by the Flavian period, this seems too much of a stretch. The helmet is all iron, and 100 years of sanding off rust is going to have some wear and tear on the helmet.

As much as the Romans liked fashion, especially in the Mid-First Century when helmets started becoming real flashy, I can't see how the Gallic A could plausibly stretch that far and still be in serviceable condition

Not a logical argument, considering that WW1 era helmets were still in use by various nations 75 to 80 years after the war. Recently in the conflict in Syria and entire warehouse of WW2 built assault rifles were discovered. Don't discount the possibility of "ancient" equipment making appearances decades after the considered lifetime of said item.
