We would ask you to study this drawing very carefully as everything has been modified or moved slightly with the exception that the high tension Bakelite mouldings and the rotor arm remain unaltered. The high tension contact points are longer owing to a relatively higher position of moulding. E. {Mr Elliott - Chief Engineer} | ||
