| X3730 Hs. {Lord Ernest Hives - Chair} C/o R. {Sir Henry Royce} Le Canadel(Henry Royce's French residence). From EP. {G. Eric Platford - Chief Quality Engineer} EP {G. Eric Platford - Chief Quality Engineer} 4/LG21.3.22. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. CARB. X4086 X4219 V3730 Sorry to hear of your failure due to the Coil. We are anxious to receive the faulty coil for inspection. Was the fault due to the low tension or high tension wires, or connections failing? Hy. {Tom Haldenby - Plant Engineer} has left Derby today with the first of the 3 10,000 miles trials' cars 5-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-II. This chassis was fitted with an all-weather body and CJ. has given Hy. {Tom Haldenby - Plant Engineer} instructions today that this car must be immediately put in use as the "express" car. He has booked accommodation on the boat sailing to Boulogne Wednesday afternoon 22nd. inst. The car was very satisfactory on its final test and its performance as regards horse-power, hill climbing etc. was very good but the engine was distinctly harsh and similar to 2-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II. The clutch did not stop very nicely when depressed although attention had been given to it similar to that given to your car. The foot brake was very effective but inclined to "groan" when coming to a final stand-still. The Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) limousine 3-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-II was used by the Sales Dept. this last week-end but they seem very dissatisfied with it and I attach a copy of a memo. from CJ. and a copy of our reply. The settlement of the carburetter job and whether R. {Sir Henry Royce} is in sympathy with using or adopting in some way, the S.U. Carburetter, is a point which requires establishing. contd:- | ||
