This locomotive was built by Hibberd in 1938 for Shell Mex and BP Ltd. in 1938, and as No. 13 was sent to the oil storage depot at Hamble on the east side of Southampton Water. Duties included work on the mile long branch to Netley, where the Shell / BP system connected to the Southern Railway. In September 1950 the loco was transferred to the Shell Mex depot at Purfleet, Essex, where it remained until February 1952. It then went to Trafford Park in Lancashire.

It was sold to dealers Cox and Danks, and was purchased from them by Broom and Wade Ltd. It worked at their High Wycombe, Buckinghamshire, depot until March 1976 when rail traffic ceased at the plant.. After two years' storage the engine donated to the Society by CompAir Broomwade Ltd., arriving at Quainton on 19 August 1978.

No. 2102 is fitted with a six-cylinder Paxman Ricardo diesel engine, developing approximately 75 hp. Drive is through a clutch and three-speed gear-box. Perhaps the most interesting feature of the locomotive is the 'Howard type' frames, built up of rolled steel channels and other standard sections. This design was developed by J. & F. Howard Ltd. of Bedford, a company that had built internal combustion locomotives during the 1920s.
