I would agree with what Crispvs has said with regards to the dating of such a helmet, however we have to also consider the Coolus type F found at Bosham harbour with an Oyster Shell stuck to it that is said to be 43-44 AD the Gallic A might just reach the Flavian period of 60-80 ish maybe even 5 or 10 beyond that. Therefore based on that you might just get away with it some where at a point beyond mid first century.
