Fundamentally we see no reason why the principle should not work quite satisfactorily provided the system is correctly arranged electrically. We in the Electrical Exptl. Dept. are working with a view to proving the satisfactory operation of 12-volts Vibrator Regulator Control on units of size suitable for our 40/50 chassis; but this involves a fair amount of careful work which takes some little time and for which we have not had, so far, the best of facilities. The Bijur 12-volt generator which we received from the U.S.A. put up unsealed a poor performance on the bench and one which would have been quite unsuitable for operation on the car. In due course this will be examined in detail and the cause ascertained. As before stated we do not consider that the method of control is wrong, but that it should be carried out in a perfectly reliable manner in order that the right results shall be obtained inservice. The attainment of such result is what we are aiming for experimentally and will be ultimately such that a large proportion of possible trouble on our present system will be eliminated. We presume that CJ's enquiry is more particularly with reference to the Goshawk and therefore it is doubly difficult to make a comparison between the cost of our own system and the Bijur system on that chassis.
