No just three screws. No nuts on the inside.

Thats another improvement then. The older design used rather prominent nuts on the inside of the tube which intruded into the operating aperture additionally to the foil spacers. I reversed the screws on mine so the nuts were on the outside but it looks as if that issue has been addressed. Perhaps the spacers have been replaced with a large "O" ring as well - I don't see the spacers on your photos ?

Yes they don't seem to be using foil spacers now. 🤔
