RML2523 is spotted in central London on 8th April 2004. Just under 1 year remained of crew operation at this date.

Here's a shot of RML2524 at Finsbury Park on Sunday 25th July 2004 - when I and many others attended the RM 50 celebrations.
This bus has been painted into a Shillibeer livery, which differs from that used in 1979.

I just made the photo here before RM25 pulled away over Battersea Bridge. This is the Great Northern livery bus which was also on the 159 during March 2005.

I took some time on Saturday 12th March 2005 to ride the 19 for one last time and I came across the Battersea base. It is rather primitive with half the roof missing!
Just peeking out is RM85 waiting to start a northbound trip.

On the same day in Piccadilly is RM1280. You can easily spot that it is a Marshall refurb, aka Dartmaster!

RML2387 with a very partial bonnet repaint is on its way south west bound when spotted.

RML2536 is at the Battersea base with RML2505 (I think) sitting behind.
