INSTRUMENT PATCH. -------------------------- The instrument patch which Sales are sending to be fitted to the instrument board of Mr. Royce's car is at present fitted with a speedometer suitable for the Continental type Phantom chassis. The dial is calibrated up to 110 miles per hour, and arranged for a driving cable speed of 670 revs. per mile. The Experimental Department are making arrangements with the A.T. Speedometer Co. for this instrument to be modified quickly for Mr. Royce's car, but in regard to the other two India 4 chassis which it is proposed to build, will you please let us know if these should be fitted with the instrument patch scheme, so that we can make suitable arrangements in regard to the speedometers for these two chassis.
