Davona I am in the process of trying to create a new standardbearer for OldGuard units based on a Sappeur, I will try to get your models etc in game if you wish to let me have a go.
I was hoping someone would!
I will PM you with some other models I need for other units.
One of my big bugbears with the way CA have done things is that they have tried to over simplify, hakos have texture split for mesh down the front middle for pete's sake so no custom shako plates that aren't symmetical.
One arm textures covers both arms in game .... no single armbands grrrr...
really their methods are a dog'd dinner!!!
This is an old image and still much to do, I have them in marching blues too:
