The non-PC 35mm f2.8, pre-"K" lenses (Nikkor-S AUTO 35mm f2.8 mine is called) with 7 elements on 5 groups. Later, the "K" (with rubber focus ring finish), Ai and early Ai-S had 6 elements in 6 groups, and the later Ai-S version had 5 elements in 5 groups.
The 35mm f2 started in 1961, so you might find one from 1969. The f1.4 versions started in 1971. My Canon FL 55mm f1.2 might be from 1969, I have not tried to exactly date my old nikkors (except my Nikkor-S•C 55mm f1.2 which probably is from 1973).
