| ROY{Sir Henry Royce}/MS. Y 146. Hs{Lord Ernest Hives - Chair}/Les.2/KT. 28.12.32. PEREGRINE ROAD SPRINGS. X3854. Will you please order a set of 4 low rating Peregrine road springs from Messrs Woodhead. 2 off, type F.100095 - 600 lbs. 2 off, type F.100099 - 800 lbs. These be exactly similar to those supplied 7.12.32. That is, without curled ends for each leaf, and should be drilled and grooved for chassis lubrication. We also intend to retain the cadmium plating as supplied on the Firth springs. If Woodhead cannot cadmium plate these springs, they will have to be plated in our own plant.
