Gearbox - Phantom III. With reference to the synrhromesh cones for "T", 3rd and 2nd speeds for production, we understand that full details of these cannot yet be instructed. In any case, however, we think that the "T" and 3rd bronze cones should be strengthened to avoid distortion by working to the thickness given on our N.Sch.4661. E/HDY.{William Hardy} | ||
