I wish to confirm the conversation that we should not deliver chassis with the original clutch owing to the fact that the present type clutch fabric fails rather rapidly, in fact, much too soon to be suitable for road work. In view of this, thicker Ferodo discs have been ordered with the holes pressed in instead of being machined, and in order to accommodate the new material a distance piece is to be introduced between the flywheel and the cover, which will be made in mild steel, and could be made from a piece of bent strip welded. In the meantime, the Order Office have succeeded in obtaining supplies and 50 discs will be delivered this afternoon or tomorrow morning in order to enable the Works to carry out the necessary changes. We are not to stop production in carrying the above into effect, but it must be borne in mind that clutches will have to be changed before they reach the customers hands.
