| Y 1775 19th April 1933. Dear Rm{William Robotham - Chief Engineer}, I understand that you are a "Minx" owner and are an authority on silencers, and I am wondering whether you would be so good as to let me know if you consider I can do anything to silence the induction roar on my "Minx". I substituted the Solex carburetter for a R.A.G. which had little effect upon the induction roar, but a great effect upon the performance of the car. I do not want you to go to a lot of trouble over this, but if you would be so kind as to make a suggestion to get over the trouble mentioned above, I should feel greatly obliged. Bkl. npe | ||
