The following is R's remark on the standardisation sheet for Switchbox for use with two-rate charge scheme providing for full dynamo output in S & T position as well as in H S & T position:-

"Personally I do not think this scheme worth the cost and complication. I cannot see exactly how it saves the dynamo difficulty to make any practical difference, also I have seen no report on any suggestion of the possibility of maintaining the rate of charge with speed by using another position of 3rd. brush. Probably no advantage in my suggestion but I should like it examined."
