All of the 345 type D9 double-deck buses built by BMMO operated their entire service with the company in standard form with fixed roofs. However, after being withdrawn, Prince Marshall (“Obsolete Fleet”) of London acquired seven examples to operate open-top sightseeing tours around London on behalf of London Transport. These vehicles were converted to open-top and repainted to overall red London Transport livery by LPC Coachworks of Hounslow and entered service with Obsolete Fleet in April and May 1975. They remained in service in London, along with a small number of standard fixed-roof BMMO D9 double-deck buses that Obsolete Fleet also operated, for about five years before withdrawal.
Details of the seven BMMO D9 double-deck buses converted to open-top as as follows…
4903 was new in January 1961 at Redditch depot, and later saw service Banbury depot, Nuneaton depot and Wigston depot before being withdrawn in December 1974. She operated as fleet number OM1 while in service with Obsolete Fleet, and after being withdrawn in December 1983, she was exported to Germany where she operated as a promotional vehicle in overall blue livery until 2001 when she revieved and overhaul and was repainted to overall green livery… See http://www.mehnert-promotion.de

At some time, presumably while with Prince Marshall (“Obsolete Fleet”), fleet numbers 4903 (OM1) and 5016 (OM5) managed to get their registration plates mixed up. As a result, fleet number 5016, preserved at the BaMMOT, carried the incorrect registration number 903KHA for a while. The mistake was only realised and corrected when someone at the museum noticed the chassis number was not what they had expected it to be!
