| COPY. C. c. to EP.{G. Eric Platford - Chief Quality Engineer} LE3/R9.5.30. re. GWP-14. SWINTON.(AT PARK WARDS). When we tested this car we found that the owner had instructed Park Wards to send the car to Smiths to have 4-wheel Jacks fitted. As you are aware, the general fitting of these is not at all good, the pipe line that they run to each Jack is just clipped on the chassis frame in a very indifferent manner, and all we can do is to inspect this and see that it does not affect any part of the chassis. The actual hydraulic Jacks are clamped on to the axle. Do you not think it would be advisable for us to go into the fitting of these, and make sure that the clamps that Messrs. Smiths use on the axles are not likely to cause any damage? I have noticed just recently on the road at least half a dozen comparatively new R/R cars on which these Jacks have been fitted, and although the Works may strongly object to these Jacks, the fact remains they are getting on a number of cars; and do you not think we should make every effort to see that as far as possible the fittings they utilise are not going to cause damage? I find that the actual ground clearance is 6½" in the front, and 6" in the rear, and with a flat tyre the ground clearance is reduced by 2½". J.L.E. | ||
