MB 90 – VEHICLE HISTORY 

MB 90   (Registration SMM 90F)   (MCW Body No. C90)   (Type 1MB1)  (Chassis  3P2R)

The name ‘Merlin’ was given by London Transport to their fleet of 665 36 ft long single deck vehicles built on the AEC Swift 691 chassis.  Although strictly incorrect, the name Merlin has remained in common use, and distinguishes this class of vehicle from the shorter SM class Swifts.  Merlins were the first standard design of omo single deck vehicle to be purchased by London Transport to take advantage of the then newly introduced government bus grants. 

MB 90 was one of the first batch of 33 Country Area buses (MB 81 – 113) delivered at the start of 1968.  She has an 11.3 litre engine rated at 165bhp.  Registration numbers in the SMM - - F sequence had been reserved, but only 13 vehicles, including MB 90, actually entered service with the SMM registration.  Most were sent to Reigate, replacing RFs on route 447, but MB 90 went to Garston for route survey work. 

MB 90’s service life with London Transport / London Country lasted barely 10 years.  She then passed through various other operators until rescued by the well-respected preservationist Chris Sullivan.  Chris returned the vehicle to its original B45D configuration and re-instated the centre doorway using parts from the scrap MBA 580. 

Today there are only a handful of Merlins left in the UK, and MB 90 is unique in being the only Country Area survivor, and also the only example of the original low driving seat position.
