| -2- Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}1/MR.20.1.39. Rubery Owens loaned us a couple of Talbot cover discs burnished but unpainted and suggest that we ask Park Wards to practice spraying on these. They will then be able to tell us, if necessary, where we have gone wrong. As Cornercrofts pointed out to us, it is impossible to spin stainless steel and, therefore, if we use stainless steel it would be necessary to have pressings. We consider stainless steel a more Rolls -Royce job, and do not think that the tool cost is exhorbitant if it were spread over all the cars using semi-floating axles.
