According to Chuck Walker's Atlas: The Ultimate
Weapon, the Atlas is vehicle #8A, "reconfigured to Atlas D
configuration." Being research & development models, relatively few of the
Atlas A through Atlas C series were manufactured (the Atlas D being the first
operational version). The Atlas A was even more interesting in that it had
only the two outer booster engines, lacking a center sustainer engine. It's a
shame that they didn't keep the Atlas in its "A" configuration (plus, the
center engine which was added is a obviously a falsey).
