We can therefore settle down to our job of work. We are proposing to prepare a list for the Works showing which parts we think are absolutely safe to proceed with, another list which shows parts which should be proceeded with slowly, a further list of parts which should be held up. We should be very glad if you would give us your views on how the parts should be classified. I feel rather concerned about the failure of the central lubrication on 18-EX. I think we should prove that it is the filters becoming stopped up on the drip plugs which caused the failure. I feel there must be a very good reason for Bijur recommending pumping every 50 miles.
