Arriva staged an interesting display of open toppers at Showbus international 2006. Nearest the camera is former Shamrock & Rambler MCW Metroliner ML12 (A112KFX), in the middle one of several Leyland Olympian/Alexander deckers from the final batch of new doubledeckers delivered to London Buses converted to open top: OA334 (J334BSH) and on the end DLP207 (T207XBV) a DAF DB250LF/Plaxton President from Arriva's first low floor London fleet recently converted to open top.
DLP207 (T207XBV) leads the trio into the Duxford airfield.
Originally Arriva London DLP1 (V601LGC) - which appeared new at Millennium Showbus - seen here on Marylebone High Road in June 2006. The low floor DAF has had its Plaxton President body converted to open top and has been renumbered by the addition of 200, making it DLP201.
Sister vehicle DLP203 (T203XBV) seen in Park Lane later that year.
The 2009 OLST contingent at SHOWBUS comprised Ayats Apollo bodied Volvo B7L VLY602 (LX05GDY) and Plaxton President bodied DAF DB250 DLP201 (201KYD) which has lost its original registration V601LGC.
