Daniel and the list, The Entry for the Atlas F-1 in MW encyclopedia, for the Atlas F1 launches show that this launch was with Atlas F1/ SGS-1 . This same configuration is used for the first Navstar launch, later changed to Atlas F/Agena. This is referred to also in the RAE tables. Other launches with this vehicle use various STAR X solid fuel rockets, so I assume the SGS is a small solid fuel stage, 1.8 metres long. The payload is A, the apogee kick motor is C , so the rocket body B is some small rocket. The only time an atlas sustainer + tankage madr it into orbit was for 1958 zeta, and for the mercury altlas launches I think. The stages referred to in the Atlas F entry are the Atlas booster and sustainer parts that make its 1.5 stage rocket.
