Victorinox, Y U make so many confusingly similar/different details and models

So, the seller claims this Vic is from 1974, as new, in box.

So far I have learned that the trilangular shield logo does not neccessarilly equal the Elinox brand. Economy Vics sometimes used these as well. OK, we solved that.
What is bugging me is this combo tool, as far as I know, the combo tool was introduced in the 80s...?

On the box drawing, you can clearly see a combo tool, not a bottle opener.
I suspect it is an economy Victorinox Waiter, NOT from the 1974, but later....
