Complaint of Stiff Change Speed
Operation - Lord Doverdale 3-AZ-46.

The latest type P.III box on which we have carried out experiments has a very much lighter gear change than the original, due to altered cone angle screw-thread cone surface, etc.

If it is considered policy, we believe that this box would satisfy Lord Doverdale; on the other hand, it would be fatal to start a precedence to change gear boxes on all the P.III that are out because some people think it is hard work changing gear.
