| - 2 - EPYT/H19.3.30. Personally, I do not see so far what advantage we have had in changing from the material which was used on the Phantom I, although I admit the material used then had certain disadvantages. Could not this material be made with a selvedge edge as we found had to be done when using the material for clutches. We also found in this case it was not a success to fix material by means of rivets, but to use staples only so that the strands of the material were not cut or broken. I notice that on the 20-HP Experimental car now running in France, the report after 5,000 miles is that squeaks have been experienced from the servo, which in this case is fitted with similar material to the Phantom II. I suggest the question of this material being properly fixed and finished off should be definitely settled before standardising. Will D/EP{G. Eric Platford - Chief Quality Engineer} please issue the necessary instructions to N. and R/D to carry out the above change, so that the car referred to can be returned to the customer as soon as possible.
