I might be mistaken, but I don't think
BF has any kradschutzen models for later in the war. Motorcycle formations were primarily something from the early years of the war. And while they apparently still existed (according to the list you mentioned in Grey Wolf), they were pretty uncommon. Because of that, I don't think
BF released any motorcycle models with Late War era uniforms.
So use the Early War formation. And if your opponent is a big enough of a twit to complain that the riders are wearing the wrong uniform, then smack him with your hard cover army list book.
