Thank you for the information and above all thank you very much for making this mod, the period of the NYW to the WSS is my favorite, so I'm sure the mod will look very good. Regarding the uniforms, I suggest you make all the uniforms based on what was worn at the very beginning, at 1689 to avoid historical inaccuracies. Because, if you introduce things from the very end it may look inaccurate at 1689 and not the other way round, as old uniforms might have been worn at the end sometimes. I don't think that looking for information regarding Sweden is very difficult as the basic uniform was very simple in most cases, based on the 1687 regulation, which made most regiments wear a plain blue justaucorps coat with the color of the lining depending on regiment, a carpus, pants and stockings with a color depending on regiment as well and shoes. There was no regulation for Officers and NCO's, so they most likely wore a fashionable skirted justaucorps to be easily distinguished from the rank and file soldiers. Most likely, the first ever Swedish regiment that received the tricorne was the Livgardet, which according to 1695 regulations (If I'm not mistaken) had to wear a tricorne, although the coat was unchanged. Cavalry was also one of the earliest sectors of the army to receive the tricorn hat, so by the start of the Great Northern War most cavalry wore the tricorne, although most soldiers except the Livgardet wore the carpus, which was quite practical, but by 1704 most Swedish regiments had received the tricorne. You can check the page tacitus.nu and Hans Högman's website:

By the way, what do you mean by saying that the Spanish had the same cut as the French by 1695? Does that mean that they received the fashionable skirted justaucorps? Where did you find that?
