No worries, this is from my update:
"The crown fits OK, the lever touches, but does not push in that much, if at all. Although I do think it sits well, slightly away from the case (just like the gen picture I posted). When pulled out the crown just touches the inside of the crown guard, but it works perfectly fine"
So the crown does "feather" touch the inside of the CG, but it causes no problems, and makes no marks/noise when turned
EDIT:
Have a look for yourself!
In fact, the way I have measured out the crown stem, I don't think it touches at all! It is very, very close and maybe it gently brushes the CG sometimes, but it feels totally free when the crown is turned
