Forgive me for posting to this thread three times in a row.
I'd like to share some comparative research I've been doing of the hats used in the film. With current reference, we can be sure that there were at least four distinct hats made for the film.
I was able to compare them using the the gold stitching on the leather (which varies from hat to hat) as well as the placement and proportion and sometimes color of the other accouterments. (The direction of the top ribbon, the size of the top leather patch, the color of the beaded peacock feather piece.)
I have numbered them for my own reference:
1. The first is what I'm calling the hero/poster hat. It is prominently featured in several sequences shown in the trailer, as well as the poster. Has prominent orange yarn on the beaded peacock feather piece.
2. The second is what I'm calling the Weathered/Bare Hat. This could possibly be a stunt, but I believe it to be weathered for a specific sequence in the film. Has no beaded peacock feather piece.
With that piece missing, we're able to see hint's to the hat's construction: the leather seam is hidden under the peacock piece. This could be limited to this piece, but I doubt it. Other hats have peacock feather, the top ribbon, and some stray tool that could feasibly cover the seam.
3. This is I'm calling the "D23" hat because that expo is where it was shown. It can't be seen in the trailer. It is also bear, missing the peacock feather piece. I think we can assume it is lost at some point in the film.
The top ribbon is more prominent, and slanted in the opposite diagonal direction of the first two hats.
4. I call this the "Exhibit" hat. I saw it in person at the San Diego exhibit.
Aside from the inherent differences in the leather pattern gold stitching, this is the other "complete hat." It has all the detailing, but differs from the "Hero Hat" in a few key ways: The top ribbon is slanted in the same fashion as hat 3. The peacock detail has prominent purple yarn instead of orange. The leather patch is raw, with no punched pattern.
Looks like they used the same components for each, combined in different ways.
That means there's a lot of room for interpretation!
