Starting an auxillia unit.

Maybe, but we know that helmets saw a great deal of service, for example the Montefortino type dated to the 70's AD, and the cross-braced Theilenhofen helmet dated to the 180's which was found at an auxiliary fort, so no, not impossible.

There ARE auxiliary soldiers depicted on the Tropeum Traiani, but they show no distinction between helmets worn by the legionary soldiers (which is what I would expect). Too many auxiliary soldier impressions rely on Robinson's out-dated helmet classifications.

Yeah, I can't disagree with any of those points! Anything is possible! Guess it all depends on what you form as your own opinion.
