Ah. I thought so. But that is not a "Roman" helmet, and chronologically also not really fitting. It would have been a quite old piece of booty at Cannae. Apart from a few pieces which probably travelled with mercenaries or by trade to other parts of Italy (and one to Greece) all these helmets stem from Apulian upper-class burials. They were in use from the 5th century onwards just a bit into the third century. No piece was found with cheek pieces, and there is no reason to assume that they were ever worn with cheek pieces. Despite the fact that you see them in "reconstruction" drawings quite often worn by Romans and from other periods. This started I think with P. Connolly and was ever copied by others, who apparently never made proper research. See online PhD thesis by Paddock, available through ETHOS, p. 78ff.
Best!
