Anyone adopted or tried a campaign hat (aka, Smokey Bear, Montana Peak, Mountie, Drill Sergeant, lemon squeezer, et al) hat in their steampunk attire?
E.g.,

It seems period correct enough, having derived from the 1840s/50s period, and certainly was made famous by Badden-Powell before the TOC.
There is a local police supply store that is having a big sale on them and for some reason a straw one in tan that is just my size is crying out to me to be used for some purpose. Certainly stiff felt may be a more period correct option, but straw seems more practical from an actual use perspective, especially since it is quite warm in my area for most of the year, and my grey felt top hat suffices admirably during that period.
