| R.R. 235 b 300 T; (N.F. 673. 22-5-19) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2876. To By.{R.W. Bailey - Chief Engineer} from Bn.{W.O. Bentley / Mr Barrington} Copy to Mr. He. Ck.{Mr Clark} x.354y BnS/W21219. RE PETROL GAUGES ON 40/50 HP. CHASSIS. Our present oil gauges I believe read to 20 lbs. pressure. It is possible that in the future we shall put our normal oil pressure up to 20 lbs. or thereabouts and it is desirable that we should increase the range of the oil gauge to, say, 30 lbs. Will you please make enquiries and ask if this modification could conveniently be arranged and when you could bring the alteration in. I do not think this modification will require a Standardisation Sheet. It might be passed in our Progress Meetings if agreement is reached. Bn.{W.O. Bentley / Mr Barrington} | ||
