Harold Whyman - Experimental Manager}9/AP.13.8.37 Further to our memo Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager}15/JH.7.6.37 and in reply to G/WFH/CA.1/DN.12.8.37, the 2 special Fort covers in question will not now be returned to Dunlops, as this pattern of tyre has now been removed from their secret list, and is being sold to the public.
