Great idea. The S*R Team is tops with this style of headgear.
I'd also like to see a set of French Lancers from the 1860's when Maxamilian was in Mexico for what Osprey calls, "The French Adventure." These hats had a very narrow top base, but nice 4-pointed flat top. Simple, yet elegant.
You can see them in the movie "Major Dundee" with Charlton Heston and
