| HS.{Lord Ernest Hives - Chair} } FROM R.{Sir Henry Royce} BI. } Copy to BI. ENOTS PETROL FILTER. X4037 Regarding the above, samples of which you sent me, the weight is excessive and the bolting is wrong, otherwise it is a very nice thing. The bolting should be near the centre of the base, and the base should be less weighty. We might consider one bolt, and a feature on the die casting to keep the filter from turning.
