The coil plays an extremely important part in the running of a car, especially when high performance is required. Owners of sports cars would therefore do well to become acquainted with the Mamba’ coil, the 12-volt model of which will spark satisfactorily under compression and run an engine with only 4 volts at the battery. It is actually available in 6 or 12 volts. The construction of the coil is of an unorthodox pattern, and enables it to meet the demand for high speed operation necessary on most sports engines to-day.

The price of the Mamba’ coil is 50s., and the sole agent is Mr. C. Desiderio, 143, Whitfield Street, London, W. 1.
