im looking for some info regarding the uniforms of the officers, drummers, sub-officers and the standard bearers för västmanlands(or vastmanlands in english) great northern war regiment. i got all the info i need on the regular soldier uniforms, so i just need the command uniforms.

At 1700 (from the Book The Great Northern War 1700-1721, and my own assumptions noted): For the NCO (Sub-officers) and Officers, they had blue lining as was the jacket itself (I tend to do a lighter blue than the royal blue for the uniform, but in theory it was probably very similar to each others). Blue stockings (tall socks).  In summary very blue!   The NCOs would have blue Karpus with silver lining.  Higher officers I would assume with hats with Silver/Gold lace depending on rank.  The standard bearer would normally be a lower officer, so the same.  As for musicians (drummers) they tended to have more elaborate lace and sometimes reverse uniform to the men (in this case yellow with blue lining).  However, I would make them, with blue jacket and some silver/yellow detailing.    Are you doing a full battalion?

yepp, full battalion
