Antilla,
The original 747's were configured 3-4-2 in y/c as this was considered civilised in those days.
It did not take long for airlines to add the extra seat on the RHS making a 3-4-3 config.
By the late 70's early 80's all 747's were 3-4-3 in y/c.
I remember SAA still had the old config. in 1981
Those were the days indeed.
