The ET42-026 dresses both halves in 112E-026 and the scenery tells them apart
by the model. Textures were keyed by the skin alone, so the B half became a
second A: not part of the set, and listed on its own. A shared skin now gets
the model in its id, vehicles are looked up by skin and model, and the
vehicle cache is rebuilt for the new ids.
