We are revising this gearbox design to suit unit construction, and are making whatever savings in cost appear to us to be practicable without risk of drawbacks. If you have any suggestions to make will you kindly let us know. It appears to us that it would not be wise to depart from our present type of synchromesh mechanism for the Wraith but that if there is any which is thought to be simpler and as good as regards actuation we should fit this scheme to a 20/25 for trial.
