Corinthian helmet without nasal?

[Dan Diffendale]

There are two small holes just above this central area on the forehead which could possibly indicate attachment of a replacement nasal

I'd have to see it to say with more certainty, but I know there are definitely Corinthian-type helmets from Italy with nasals attached separately. I'll see if I can get some pictures for you.

They are subclassed as "Cretan" because most of them were found in Crete.

Again, the examples I'm familiar with are Italian.
