It's not a balustrade Simon. Haven't used that word in years. : )
Me either, Scott. It's funny some inessential words stay in your memory for the lifetime once learned while other essential ones don't.
First I thought it was some sort of a vault door knob, you know that round thing you turn to open it, then I realized the background looked like outdoor so it can't be it...
Getting harder and harder which is good.
EDIT : Well done, Yiannis! Impressive! And good night, Scott. Sweet dreams.
