St. Augustine Florida Excavated Spanish Morion

[fernando]

Apparently morions are often called cabassets, a more generic name.
Morions do indeed have a comb, while the cabasset has a little appendix on the top, called pear. Both versions were used by Spaniards and Portuguese.
This example has all looks to be original and therefore dated from the beg. XVI century.
There are a couple members with a lot of knowledge on these things.
