No. 9037 was built by D. Wickham Ltd., maker's number 8197, and is one of a batch of five ordered by the Ministry of Supply of 28 May 1958. It was delivered to the O/C Bicester Detachment, No. 1 Railway Group, R.E., No. 3 Camp, Arncott Depot, Bicester on 20 November 1958. The engine is a Ford side valve petrol industrial engine, which is very akin to the Ford car engine of the 1950's, with a three speed gearbox. It has totally enclosed bodywork. 9037 is the army number and it worked for them for twelve years, being offered for disposal by tender near the end of 1971. It arrived at Quainton from the Ministry of Defence, Graven Hill, Bicester, on 15th August 1972.

It is currently being extensively restored, with its engine run for the first time in December 2003 since its last run in around 1972. The underframe, axles, suspension, and gearboxes have been restored, but there is much more left to complete.
