At its launch, the B95 cost £659 (equivalent to £ today). Chassis numbers followed on from the SE492 series, and chassis number 670 (the earliest known B95) was registered at the end of March 1959. The first B105, chassis number 686, was delivered about one month later. Series production continued to chassis number 835. A separate batch of about 12 cars (chassis numbers 850 to 861) appear to have been made for Mantles Garage in the summer of 1960, which used some chassis parts and the bucket seats of the T60.
