With reference to Rm{William Robotham - Chief Engineer}/Les.7/JH.27.4.37. and the failure of the tubes of the cheapened side spare wheel carrier to LeC.5314, we suggest that the welded in distance pieces at the base of the tube be deleted and this end of the tube be restored in design to that of the present standard side spare wheel carrier. As, however, similar welded in distance pieces at the top of the tube for the attachment of the wheel carrier plate have not failed, we suggest that these be carried on with. The same remark applies to the thin gauge of wheel carrier plate and the lightened aluminium die cast centre. Since, however, the wheel attachment bolt scheme appears to be quite unsatisfactory, we suggest that it should be dropped and replaced by the present standard bolt lock design. In the meantime, we shall take the opportunity of giving you a cheapened design of this standard wheel attachment bolt. The wheel carrier brackets of Wraith III. design shown on LeC.5314, and which are cheaper than those now on production we suggest should be persisted with. The same remark applies to the special bracket under the spare wheel made under the same piece. We suggest that the scheme should be fitted up again according to the above revised specification on the bumper chassis when it is again being run, and also on the next 10,000 miles car.
