An update on these with WIP on the officers, which are conversions based on Spanish napoleonics by Perry. Perry have a number of different command packs for the Spanish which can easily be converted to look like they are wearing Swedish uniform, either the m/1802, the m/1806 or m/1807, with or without plastrons (the Spanish uniforms seem to have gone through similar changes during these years).
I will do enough for at least two 24-man battalions of the Hälsinge regiment. These have a very simple blue and white color scheme, which is good as I need to do so many of them. Thanks to Chad for the templates for the flags!
