Re our memo. ref. Hs{Lord Ernest Hives - Chair}/FJH.{Fred J. Hardy - Chief Dev. Engineer}20/KW.4.6.35, asking you to build up a steering box so that the Adamant Engineering Co. can try the cams and rollers for themselves.

As we propose to use the SpectreCodename for Phantom III gear on the 25 HP. we shall require both left and right hand cams, and accordingly we shall require both left and right hand rockershafts for the above steering box. Will you please make both rockershafts.
