The broad brimmed hat with the feather seems to have been adopted unofficially by the British Army serving in South Carolina ...
Thanks,
Dan!
And, it's actually a much more attractive hat than the tricorne ...

Since we are not at all nit-picky here at GW-PC about the uniforms that our Playmobil toy soldiers wear, I probably shouldn't even have asked the question. However, I was a bit curious and I really do appreciate your providing a quick and very informative response,
Dan!
Thanks again and all the best,
Richard
