| DY.{F R Danby} FROM DA.{Bernard Day - Chassis Design} Copy to HS.{Lord Ernest Hives - Chair} SECRET SS.{S. Smith} FRAMED INSTRUMENTS. X7530 / X4038 Herewith we send N. sch. 2836. shewing the revised framed instruments containing the K.S. gauge and the green lamp. We have inserted the latter in spire of the fact that it may not be used because it is easier to take it out than to put it in. The K.S. gauge is standard except for some slight modifications to the fixings which no doubt you will take up with Hobson's. All the other instruments are as now except for slight changes in the positions of the pips on the flanges. We have also shewn on this drawing the suggested marking on the knob of the shutter controls. We should like Derby to verify that this is the best position and size for the marking. We also indicate the modified flange for both this and the starter button. It will be seen that we have altered the material of the outer frame from aluminium to brass so that we can thin it down. We suggest the joint can be sweated or possibly hard soldered. We are sending you under separate cover a model of the K.S. gauge which Hobson's have kindly lent to us. When you have finished with it will you please return it to them in London. DA.{Bernard Day - Chassis Design} | ||
