| 1370. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}1/MH.{M. Huckerby} 9th. January 1939. Messrs. Dunlop Rubber Co. Ltd., Fort Dunlop, Erdington, BIRMINGHAM. For the attention of Mr. Price. Dear Sirs, With regard to your visit with Mr. Sharpe on Saturday, the following points were discussed:- We agree to your drawing CDO.3174 as a means to overcome the foul between the spoke heads and the wheel hub. You are going to let us know whether this modification will be introduced during the order for 300 sets of Wraith equipment which you are now making. You said you would send us five 16" wire wheels of the latest type, having 5/16" diameter hole through the valve. These will be used with the special inner tubes you are making up for us. You said you would send us a revised blue print of this wire wheel showing a plus or minus 15 limit on the dimension of the rim to the hub. If the light-weight 4" rims are not normalised we will send you some centres so that you can make us up another set of wheels. Yours faithfully, for ROLLS-ROYCE LTD. | ||
