| R.R. 235A (100H) P 723. 23.II.10) E.P. 7957. 21st December 1910 Mr. Nadin. 21/12/10 R1/D211210 Please get off at once pattern for exit nozzle on silencer so as to give opening 1/4" wide instead of 1/2" as at present. Large numbers are wanted badly for present cars and all those sent out with larger nozzle. This is to stop the booming noise which is thought so very objectionable in closed cars. This is very important and urgent. Have several patterns if need demands. Malleable iron very suitable.
