The BMMO, better known as Midland Red, was unique in that between 1923 and 1970 , it designed and constructed most of its own vehicles.One such was the C5 coach which was first introduced in 1958.This 37 seat coach was based on the Midland Red's S15 dual purpose bus, but the striking front and rear ends disguised this fact.Between December 1965 and July 1969 , 45 of the C5 class were modified at the company's Carlyle Rd.works, to render them suitable for bus work.The most obvious external difference, besides the all over red livery, was the inward opening passenger door which necessitated the shortening of the attractive wrap around bumper.
