Oh, nice sprites. I especially love the Swedish sprite, wearing the beautiful m/ä-uniform.
However, I think the uniform depicted is the m/1845. ?
The trousers should be blue. (White trousers were only used during the summer, so for most of the year trousers were blue)
The yellow "passepoil" around the edges of the jacket should be removed.
Could you pass this along to the Armé Museum here it Stockholm, as their uniforms are wrong too?
