Whereabouts of Late Roman ex-Guttmann helmet?

[ValentinianVictrix]

I'm sorry Evan but your wrong about the cuirasses on that column. On my recent research trip to Istanbul I was able to examine several framents showing infantry in muscle cuirasses from the Column of Arcadius. They have rims around the neck, arm holes and around the bottom. They are also smooth to the eye and touch. You need to look at my Flickr photos. The helmets are almost identical to this helmet but most have brow guards as well.
