Lockheed L-1011 Tristar Version Codes

These numbers include 385-1, 385-1-14, 385-1-15, and 385-3“. (Source:  L-1011 Airliner Tech Series book)

Just to throw one more wrench into this, 3 designations that never got built:

L1011-385-8M, DC-10-30 competitor, never got built, pity…
L1011-385-4 Tristar 600, Twin Engine
L1011-385-9C, sometimes called L1011-700, L1011 for mid-80s introduction with FBW, GE/RR/PW engine options, winglets on some drawings… Lockheed MD-11 competitor. design never progressed beyond drawing board, killed with L1011 program in early 80s.
