I don't know, MoGo. One of my characters is a early post CW trader going into Indian country and among the settlers of the Rocky Mountains. That way I can wear anything that might have been bought for, or taken in, trade along the highways and byways and low ways and noways I travel.
F'rinstance, I lost my hat in a windstorm and had this really big derby that had been on the wagon for months. No one wanted it so I slapped it on my head. Later a Shoshone woman traded me the hatband for a pound of sugar and her man threw in the quilled and wrapped feather for some tobacco.
It doesn't matter to me how wide-spread or common things were or when they were worn as long as it was during or before my period. Until I sold it for about 3x what I had in it, I carried a Scottish flintlock pistol as a backup. I've regretted selling it since I closed my fist around the money. The gun cover I just made was a MM era piece for a short rifle I once carried, a .50 flint converted to percussion trade gun with the barrel cut back to 24". A lot of my stuff is Revolutionary War period or mountain man era because I kept it from when I was doing that schtick.
