Bailey - Chief Engineer} Da.{Bernard Day - Chassis Design}1/HP.20.6.36. Bentley Jacking System. This is to confirm having handed to you a print of N.Sch.4830, together with the sample jack with 9 3/4" lift recently supplied by Dunlops. On N.Sch.4830 the jack head is made solid with the outer screwed sleeve and the upper end closed by a plug. This sleeve with solid head is the only new piece on the drawing and the idea is that you should make one of them and fit it into the existing sample Dunlop jack. In dismantling the jack to do this it may be found that some damage will be done to the stops, especially to the upper stop on the guide sleeve, and also to the inner screw where it is pushed into the square on the bevel. No doubt as little damage as possible will be done and it is expected it can be repaired by welding or soldering, in this particular case. The tracing of N.Sch.4830 is attached to By's copy, and it is hoped he will get in touch with Dunlop's with a view to their making jacks on the lines shewn on this drawing for production.
