RECEIVED 20 NOV SPRING LUBRICATION. -------------------- Referring to Mx{John H Maddocks - Chief Proving Officer}9/T.15.11.28. it is not a simple matter to clear up the above issue. I have discussed the question further with Mx.{John H Maddocks - Chief Proving Officer} who will continue to run the springs he has treated as described in his memo to see how long the simple treatment he carried out will be effective. In the meantime Mx.{John H Maddocks - Chief Proving Officer} will fit to all springs, pieces of felt in a similar position to that which he fitted to the pair of springs referred to in his memo. The rear spring on Phantom will not need it, but instead the existing material should be folded over to lie along the back of the spring. This is not a final solution as the felt will not retain the oil, and when the oil is used up it cannot be replaced by injecting oil through the lubricator, but the gaiter will have to be undone and the felt re-oiled and replaced. and F.{Mr Friese} Dept. Will Mx.{John H Maddocks - Chief Proving Officer} let O.O./know what he requires, and it will be ordered up and also added to the D.O. Part List as the best compromise we at present know of. The position of the lubricator has been fixed in its present position by the clearance question and accessibility, and it is precisely the lubricator position which is the main difficulty, as it is not a simple issue to ensure oil reaching the upper plate tips. We are preparing a scheme which may be possibly thought elaborate, but I see no simple method of attaining the desired goal, but I think the one I have in mind will be effective. BY.{R.W.
