PN {Mr Northey} 1/EH4.1.27. 9-G-3...20 h.p.Experimental. --- Unfortunately, owing to indispostion, I was not able to test this car over the holidays more than a very few miles, and it was sent back to Hs. {Lord Ernest Hives - Chair} immediately after Christmas. The rear shock absorbers were not of standard description in design; they were not effective enough, and consequently the car was able to jagger on a roughish road if the brakes were applied hard. The amount of power available was very pleasant, the engine being very little more rough than many of our standard engines. The steering was quite nice, and one felt the advantage of the larger low pressure tyres. Without the 50-50 mixture of Benzole and petrol, the detonation was altogether more than could be allowed in practice. I agree with other points referred to in CWB9/GM30.12.26. PN. {Mr Northey} | ||
