Fully tested and guaranteed refurbished SIBA black box system. Fitted with all new wiring, new terminal block, HT lead and spark plug connector. Ideally suited to restoration of pre-1959 Messerschmitts. Fitted to all Messerschmitts from 1955 to 1959 up to chassis number 68643 but may be used to replace later Bosch systems. Original wiring colour matches factory standard - see attached drawing for details.
Messerschmitt dealers were notified by a general newsletter dated 6 April 1959 that Messerschmitts built from chassis number 68644 would be fitted with Bosch electrical equipment. This included changes to the Sachs Motor crankshaft and crankcase dimensions
