| From FERODO LIMITED. Sheet No. 2 Dr. F.{Mr Friese} Llewellyn Smith, Messrs. Rolls Royce Ltd. 9th. April 1936. For the above reasons we should never consent to using Litharge in a rubber mixing for our particular purposes, but we would be prepared to use Atomised Lead for the purpose of conveying additional fade or additional weight, should our product compare unfavourably with Hycoe in this respect. I trust this answers your question fully, and remain, Yours very truly, FERODO LIMITED Mhongley CHIEF CHEMIST & DIRECTOR. | ||
