SpectreCodename for Phantom III Marles Steering.

As a result of the examination we have made of the steering of SpectreCodename for Phantom III III, we agree that we should supply the Adamant Engineering Co. with a steering box and rockershaft etc., so that they can try the working of their cams and rollers for themselves.

Will you please build up the necessary parts for the above. The box need not have an outer column attached and the steering tube should be a light press fit in the cams so that itcan be used with different cams. We suggest that the back half of the box should be cut away like the one you already have, to enable the working of the gear to be examined.

When you have completed this box we should be glad if you would build it up with a cam and rockershaft complete, so that we can demonstrate the working to the Design Dept.

In view of the possible necessity of ordering 8 cams at an early date, the above is urgent.

Hs{Lord Ernest Hives - Chair}/F.J.Hardy.
