Yes - very interesting flying.
My first intiation to the CC NDB approach was in VC10s back in the '60s. I remember some eye-opening approaches in bad weather. Flying up from Cheung Chau towards Stonecutters in low cloud with the windscreen wipers zip-zapping away, it was like flying through a letter-box slit - hills close on either side, solid cloud only a few feet above and the sea not far below. It was a real team effort.
Does anyone have an old CC NDB approach chart they could post here?
