Indeed it does!
I managed to drill off the head of the screw without damaging the plastic lens.... happy3 happy3

Discovered some clever person had started the screw cross threaded. But with it all apart I was able to re-cut the thread from the back, un damaged side of the brass top hat using a good screw.

Now all I need is a new screw!
