I'm currently biulding an early Stug IV of 17th SS Pz Gren Gotz Von Berlichingen during the Normandy battles. This is the only div. I have positive reference of having this vehicle. In all my references of battles where Stugs are mentioned, they are Stug III. Is this because of the resemblance of the two vehicles, and the fact that thousands more Stug III's were produced than Stug IV's, that any Stug IV's were mis-identified as Stug III's? I also have a late model Stug IV and would like to use in a diorama, but have no reference for this vehicle in any late 1944 - early 1945 actions.
