| 346. Fm. BY.9/N.30.9.37. Re: Phantom III - Front Suspension. Referring to RHC{R. H. Coverley - Production Engineer}/SB.{Mr Bull/Mr Bannister}1/MJ.21.9.37, giving the comparative costs of the Main Spring Housing as produced in mild steel forging, maleable casting, and aluminium die casting, I consider we should introduce aluminium die castings at the point mentioned, therefore, will you please issue a standardisation sheet covering this modification.
