Why it matters
The C-type Montlhéry Midget was MG's first production racing car, a customer version of the EX120 record car that first exceeded 100 mph for a 750 cc car. It won outright on its debut in the 1931 JCC Double Twelve at Brooklands, and 44 were built.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
After the experimental EX120 exceeded 100 mph at Montlhéry in early 1931, MG put a racing version into production. The C-type used a 746 cc four-cylinder engine, with a supercharger available, and a four-speed ENV gearbox. In May 1931 it won the JCC Double Twelve outright at Brooklands and took the team prize. Production ran from 2 May 1931 to 8 June 1932, and a cross-flow cylinder head was introduced during the run.

Identification guide
How to tell an original from a replica or later conversion.
The C-type has a doorless open two-seat body with two large humps on the scuttle and an opening rear section housing the rear-mounted fuel tank. Wheelbase is 6 ft 9 in on 19-inch wire wheels. Early cars used the M-type cylinder head with inlet and exhaust on the same side; a cross-flow head arrived mid-production.
