Hi Florent. These look like the 39-333 and 39-334 Dual-Arm Operators with the extra small link arm. Please compare. For new covers and handles, see the 39-107 and 39-114L sold separately.

Thank you, this is super useful!
one more question, do you know if the piece that fastens to the window frame is part of the kit? See the small highlighted section on the bottom left of the attached picture.
thanks again for your expertise!

Yes! That is a stud bracket, like the 39-516. Yours looks a little unusual, though; I am not sure what's going on with that bent edge on the bottom. Perhaps it was modified to fit the window for some reason. See if you think the 39-516 or 39-517 could fit the window instead.
