Thank you for these further responses.
I am most appreciative of the help given by you all; very kind.

At the 1.10 and 1.40 stages of the video, the slats look to be retracted. At the 1.54 point they seem extended then moved in and out by the serviceman.

Perhaps Galland's observation will remain unexplained. In the initial post, he is cited as pulling them out and then letting them snap back. Perhaps his memory was incorrect, or the translator / editor inaccurately worked on the comment. The only other thing I can think of is that more than one system of slat operation was in use at the time.

My first model will have the slats retracted. I'll save the resin bits for a second.

Again, thanks for your thoughts,

Michael
