Gallic helmet types are fine Andy! we have evidence to suggest that auxiliary soldiers wore them too.

Send me your email details in a PM Andy and I'll get the info off to you.

With regard to the XI.. They were indeed sent to assist in putting down the revolt..

The expeditionary force consisted of the victorious VIII Augusta, the XI Claudia pia fidelis and XIII Gemina, the
XXI Rapax (which had been one of those supporting Vitellius), and, of the recently recruited legions, the II Adiutrix.
These were led across the Alps by the Great St Bernard and Mont Genevre passes, though part of the army took the
Little St Bernard. The XIIII Gemina was summoned from Britain, and the VI Victrix and I Adiutrix from Spain.
