| To Wor.{Arthur Wormald - General Works Manager} from CJ. To EP{G. Eric Platford - Chief Quality Engineer} from CJ. To Hy.{Tom Haldenby - Plant Engineer} from CJ. To Hs.{Lord Ernest Hives - Chair} from CJ. To BJ from CJ. Goshawk - 10,000 Miles Trial Car. 1. Referring to my memo. CJ6/E26/4/22, if before its receipt the 10,000 miles car has arrived at Derby, I am very anxious that no part should be replaced unless it has broken and is no longer serviceable. 2. In that case, I should be informed what part has broken, why it is no longer serviceable and how it has been replaced. 3. I can imagine that Derby will wish to examine the car to see what parts have worn. 4. But I do not think the 10,000 miles is sufficient and I should like the car to be returned to France, and to be driven at the highest possible speed up to 20,000 miles, so that we can ascertain what parts, owing to fatigue, may possibly succumb. Please report to me immediately on this proposal. In the meantime do not dismantle the car except so far as it may be necessary to replace parts which have already succumbed and are no longer fit to use. CJ. PS. I do not see any objection to your examining the wear and tear which has taken place, if you consider that thereby you will obtain useful information which can bring about remedies in the early series but I am very anxious that you should not take up wear and tear but that the car should continue to run with its present wear and in exactly the same condition as it comes off the road for the next 10,000 miles. We want to imagine that some one has bought one of these cars and has run it hard for 20,000 miles over bad French roads and we want to arrive at what the condition will be at the end of 20,000 miles, not 10,000 miles.
