| X442S. Chassis. Hs{Lord Ernest Hives - Chair}/Fm.1/AD. August 24th, 1932. Mr. Bernard Hopps, Dornoch Hotel, Sutherland. Dear Mr. Hopps, Thank you for your letter of the 22nd inst. With reference to your queries, it would be quite satisfactory if the A.15 plugs are made to the same dimensions as the little K.L.G. plug which I have sent you. In case you have not already received it, herewith sketch of its principle dimensions. With regard to the HD.{Mr Hayward/Mr Huddy}3 plugs, at present it is proposed only to use these on the Phantom. I do not think there is any prospect of our departing from our present practice of fitting the K.L.G. to the 20/25 more especially as their K.1 plug is such a satisfactory product. It is possible, however, that there will eventually be some more business for you in the 14 mm. size. I shall be at Coupar Grange, Coupar Angus, Perth from the 27th inst. for 10 days or so should your car break down on your run South and consolation be required. I hear the salmon fishing this year has left much to be desired and hope that the grouse will not be so un-accommodating. Yours sincerely, | ||
