| TO GA. FROM R. {Sir Henry Royce} c. to BH. RG. {Mr Rowledge} c. to HCH. PX. c. to HS. {Lord Ernest Hives - Chair} ORIGINAL RE. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)). GEARBOX FOR SIDE LEVERS & 4 WHEEL BRAKES. X 5940 X 4247 Referring to your memo. regarding four wheel brakes for Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)), we have I understand stopped the gearbox we have designed for side levers without four wheel brakes. We shall be pushing forward the designs for a box which we had in hand exactly like EAC.1. somewhat simplified for side levers and multi-plate pattern "Servo" for four wheel brakes. I believe it will be our best policy, and certainly easiest understood, if we announce that after No. so-and-so 20.HP., these chassis will be fitted with side levers, and can be supplied with four wheel brakes if desired, at £50 extra. That is, we do not attempt to fit four wheel brakes with the present box, or with any box having central levers. To enable us to make this change at a suitable date we must stop production of front axles, and gearboxes, and change speed levers for this chassis. The date at which we can supply this gear-box (I suggest March) will be the date at which we can supply side lever cars with, or adaptable for four wheel brakes. R. {Sir Henry Royce} | ||
