| Expl: Dept: 44038 8th. Jan. 1927 HS{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG. Messrs. H.M.Hobson Ltd., 29-31 Vauxhall Bridge Rd., London S.W.1. Dear Sirs, With reference to your letter of the 6th.inst. We have now decided that perhaps the most satisfactory method of getting the gauge fitted to the car at present at the Coachbuilders is to supply with you with a tank in which to fit the gauge and then to change the tank over at the Works here, at the same time fitting up the air line and the instrument board. We should be obliged if you could let us have a dimensioned blueprint of the gauge which you propose to fit to our 40/50 HP. tank and we will then go into the matter and see where we should like it to be placed, the object being to get it as near the centre as possible and so minimise errors in reading due to road camber etc. With reference to the improved design of face. We realise that this will take time to produce and also as it is a departure from standard, will be slightly more expensive than the type of gauge we have already had. However, we should like to know when you anticipate you could let us have a gauge with a face on the lines indicated so that we can ascertain whether the alteration makes the reading satisfactory. As the car will be at the Coachbuilders a month, we have approximately that period in which to prepare this gauge. We estimate that the max: permissible overall length for the major axis of the gauge face is 4". Yours faithfully, | ||
