Great looking additions to your army.
One question though because I am not that familiar with the prussian army; are you certain that in the period you want to portray the grenadiers wore that grenadier hat? I always thought that in the first years of the FR they wore the same bicorn/kasket as the other infantry just with a grenade on the front.
Also, ween't the grenadiers combined into grenadier battalions and not with their parent formation?
Hope you do't mind these remarks
