Dear Sirs, With reference to the sample Heater supplied to you for test, we have just completed our investigations and find that better results are obtained if the twin outlet casting is arranged as per sketch below. Vents If the other way round the delivery of air is a little unequal and the volume reduced. This is well worth noting. Yours faithfully, For S.SMITH & SONS (MOTOR ACCESSORIES) LIMITED. GS.
