Thanks a lot, Olivier
very much appreciated. And it is nice to notice that Pierre Leyvastre's 33 years old article is still relevant. It was a bit older than I remembered and in late 1973 the magazine wasn't yet divided to Air Enthusiast and to Air International and was a monthly publication called Air Enthusiast.
I have a question on MS 410s but opened a new thread for that question.

Thankfully
