The Turning Lock you describe is with the lady finishing the Spin Turn facing diagnal to the centre. The most popular Turning Lock you will finish your Spin Turn facing down the LOD.
The Spin Turn used is called an Overturned Spin Turn.
There are three types of Spin Turns. One is under turned. Then there is the normal Spin Turn and last the Overturned Spin Turn. Each will have different amounts of Turn. You will not do a Turning Lock from an underturned Natural Spin Turn where the lady finishes facing diagnal to the centre against the LOD. Then man is the natural opposite in each case. Keep going.

"Yes, no ( foot) swivel on 1, but body turn present. right ?"

Depends on what you mean by 1.

If you are going by the book description, 1 would be the first step of the natural turn, and would have no foot swivel.

If you are counting 1 as the first step of the spin turn action, it's more complicated. The written description is of a partial pivoting action on that step (though not as complete of one as in the natural pivot turn), and a pivoting action is only semantically different from a swivel action.

But in actual practice, most serious dancers are not doing much of a pivot there at all. Instead, they are placing the foot with some toe in for the backwards partner, and using body rotation only. This is a much more powerful and dynamic way to do it, and really improves the progressive flow. It's even fairly common to dance consecutive pivots with something of this technique - actually spinning the ball of the weight bearing foot on the floor is a fairly precarious thing to do. Compare the precarious look of beginners who may take the written instruction over-literally, to that of more experienced dancers who move through the step, rather than trying to balance and spin on the ball of foot.

(Another camp of champion-quality dancers does a heel pivot instead of a ball pivot, or the more common body-turn-only)

Nobody has mentioned that step four if taken down the LOD will go farther than a step that is taken diagnal to the wall. That is why I asked how long should a Spin Turn be using an ordinary sized door which is 32 inches wide as a guide. Also remembering that the winner is not the one who goes around the room the quickest.

"That is why I asked how long should a Spin Turn be using an ordinary sized door which is 32 inches wide as a guide."

The spin turn, like any step, should be the proper size for the situation in which it is used.

Without knowing the details of the situation - dancer's heights, ability, goals, artistic ideas, preceding and following actions etc, we can't determine the proper size of the step.

If we take a taller dancer we have Jonathon Wilkins compared to and a very short dancer, the 5th placed couple at the recent British. Would you expect to see a greater distance coved on a Spin Turn by the taller couples than the not so tall. Very interesting comment from Michael Barr. Over the years most of the champions have been smaller in stature.
