Hs.{Lord Ernest Hives - Chair} ---------------- GOSHAWK CHASSIS. REAR AXLE RATIO. ---------------- With reference to BJS/H.{Arthur M. Hanbury - Head Complaints} 11.12.22. we do not see any difficulty at all in regard to accepting the position put forward by myself to the effect that Sales should specify the axle ratios which would be fitted to all demonstration cars, providing the information in regard to the axles is given to us sufficiently early to enable the Works to get ahead with the requisite number of axles called for. We quite agree that Sales' knowledge of the requirements for demonstration cars in different Countries is better than our own, and therefore we feel that if Sales will accept the responsibility for fixing the axle ratio and do it in sufficient time to enable us to produce the axles in the quantities required, as mentioned above, all our difficulties will disappear. We have procured from the Test Dept. and give below a list of the Goshawk cars already delivered or being delivered, showing the axle ratios fitted. 41-C-9. India. 14 tooth axle. 40-C-4.
