| Mis. To RMC. From Hs{Lord Ernest Hives - Chair}/Am. PEREGRINE ENGINE UNITS. Since the cylinder head on Peregrine has been settled, we should like to ensure that every unit is fitted with the final type which is the large valve turbulent head. At the present moment we are short of two of these heads, i.e. for No.1 & No.4. units. Will you please therefore produce these heads. Hs{Lord Ernest Hives - Chair}/Am. | ||
