| Wd. {Mr Wood / Mr Whitehead} from Hs. {Lord Ernest Hives - Chair} x4159 Hs {Lord Ernest Hives - Chair} 2/LG19.9.21. "SIMMS" PETROL LEVEL INDICATOR. We should like you to bring the following points to the notice of the makers of these Indicators. We have had failures with this type of gauge owing to condensation occurring on the inside of the glass and the moisture causing the magnetic needle to rust and stick up. We should like to know from the makers what they recommend in order to overcome this trouble. We should also like to know whether they make the moving arm type of instrument which can be fitted in any position in the tank and which does not have to be fixed vertically.
