From what I've read about proper GAoP headwear it is pretty much the cocked hat, monmouth(sp?), and thrum(sp). I've seen another hat style, a bit taller than a tricorn, flat on top, and the brim is down. If that is the proper way to put it. Somewhat like a pilgrim hat without the buckle.
Right now I'm watching Yellowbeard, not the best source for piratical ideas I know... But, Blind Pew is wearing that style of hat.
Is it historically accurate, if so does it have a name?
Thanks,
Pantless Pogue (still)
