| Hs. {Lord Ernest Hives - Chair} C. to By. {R.W. Bailey - Chief Engineer} X4261 Y4261 X2628 ROY {Mr H. Royce - Buyer} 6/FJ26.7.22. Following our conversation, I would confirm the arrangements made that you will let us know the poundages of a set of 40/50 HP. Axle Springs you require for test purposes so that we can get a set made up in accordance with our present standard practice on the 40/50 HP. but black instead of bright finish. In the case of the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)), I understand you will arrange to test out a set of black springs already in your possession with taper points and let us know in due course how these compare with our present standard Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) practice i.e. black springs but with the points left square and tapered instead of pointed as outlined above.
