RE MICHELIN DISC WHEELS FOR 20 H.P. CAR.

Referring to your memo DA{Bernard Day - Chassis Design}1/CB6/5/19, would you kindly note that Mr. Royce says, "adopt scheme N.58, using 105 m/m tyres on the front and 120 m/m tyres on the rear wheels, adopt pattern of hub shewn on Lec.1063 as regards profile."

Further to the above, would you kindly note also that the plug in the hub cap should not be used, as it is desired to prevent the driver from over^filling the hub with oil.

E.{Mr Elliott - Chief Engineer}
