Midland Red introduced its first production BMMO underfloor-engined single-deckers in 1946 following wartime development work. The operator was years ahead of the major bus builders who did not offer underfloor-engined models until around 1950.

The bodies were very modern for their time and were built to Midland Red design by Brush and Metro-Cammell. The first few hundred were 27 feet 6 inches long and seated 40 passengers. The rear axle was placed unusually towards the back so, when dimensions were relaxed, Midland Red was able to take advantage by lengthening them to 30 feet to allow another row of 4 seats. This bus has been shortened again to original length.

The first 100 underfloor-engined single-deckers were known as the S6 type (S1 to S5 were wartime prototypes). 3036 was built at the end of 1946 and was first licensed on 29 February 1947. It was despatched to Charles H. Roe at Leeds for lengthening, re-entering service on 5 September 1953.

It spent most of its life at Hereford and was withdrawn at the end of September 1961. It was sold to B. French Ltd., a Kidderminster-based electrical contractor, becoming one of the few postwar BMMO buses to escape the scrapyard. The new owners stripped the interior and refitted it as living quarters for staff working on power lines in Scotland. It spent the next 15 years 'on location' in some of the remotest areas of Scotland. Fortunately, when B. French ceased trading in 1976, a gentleman dealing with the disposal of the company's assets realised that the bus might have historic interest. He contacted Midland Red who passed the information on to us. 3036 was purchased and transported by lorry from Perth on 7 July 1976. A sister vehicle was later acquired to provide spares and interior fittings. A set of seats has been located. Major work has centred around the body frame, which has been shortened to original length, and engine.
