Is There A Gladiator Helmet database?

[richard robinson]

I have just read (although i think i already knew) that there were about twenty gladiator helmets found at pompeii/herculaneum- several of which were secutor helmets. Try as I might i can only find two of the latter-and then with that frustrating problem of not being able to get an all round view.
So
Is there a database on RAT ??( i have not found it thus far if it exists)
or any where else for that matter??
Hopefully somebody knows, :?
