Just trying to keep the War of 1812 requests in one place rather than starting multiple threads on the same subject ;) It struck me another uniform type is missing - the only British Highland unit that served in the war was the 93rd Foot (Sutherland Highlanders) who wore tartan trews and undress bonnet (similar to a tam o'shanter) rather than the kilt and feather bonnet:

However a few Canadian-Scottish militia units also adopted the same style of dress so perhaps a good subject as it isn't covered by the existing Napoleonic sets:



(Also it must be said, many of the existing Scottish Napoleonic sets are pretty bad with tartan schoolgirl mini-kilts! ;) )
