Anatoly Zak, 2011: "A scale model and a blueprint apparently depicting an early version of the R-7 missile, possibly designated R-6 -- a missing link in the Soviet rocket genealogy. A one-chamber engines shown on the model, probably represent RD-105/106 designs or their derivatives. According to Russian sources, this version of the rocket would have a liftoff mass of 170 tons and have five (or four) individual launch platforms for each booster stage".
