ABOVE: An AEC Regent-III RT on route 107A at the Arkley Hotel in (presumably) the 1950s.  The photo was posted on Facebook by a volunteer archivist at Barnet Museum and relayed to us by 
Nick Dean.  See reply 
W9/91.  Pity they got rid of that 'roof box' in the later RTs!
BELOW:  The Arkley in 2017, taken from the bus lay-by in the rather complicated 
traffic system that now exists.
