Thanks once again for the follow-ups to my original enquiry. This is proving an intriguing thread.
Perhaps it is about time I posted the streetmap.co.uk page showing these sidings:

Brent Junction refers to roads, not rails. The large building NE of this road junction is the Royal Mail’s Princess Royal Distribution Centre, which from the 1990’s has denied us the opportunity of seeing major postal traffic at London’s Main Line termini.
The River Brent flows roughly north to south near to the A.406, so this suggests that Willesden Brent sidings are those stretching from here in the ‘Up’ direction towards Willesden Junction.
Moving in a ‘Down’ direction to the west of the A.406, you can see the sheds for the Bakerloo Line where the DC lines loop north of the WCML. and I believe the ‘through shed’ and adjacent sidings below the DC track are for WCML carriages. Can anybody confirm this?
Below the carriage sidings are two marshalling yard type blocks of sidings joined by a single line, so are these the Wembley sidings added in the 1990’s?
This complex would make a good subject for a video. All that is needed is a camera man in a helicopter and a well briefed commentator. Any volunteers?
