While the goggles and the helmet are still in the game (as separate objects), the scarf was cut entirely, though it may have been replaced in concept by the different bandanas.
In the final build of the game Elder Maxson wears a unique coat, the mesh of which includes the BOS officer uniform.
In the final build of the game Lancer Captain Kells wears a unique variant of the Brotherhood fatigues. Most likely replaced by the Science scribe's armor in the final build of the game.
