The different size of trunk induction pipe which I think will show considerable difference at high speed compared with the smaller one used in 1906. 3. Any testing that can be done in the new testing shop with the corrected calibration of the dynamo under any variation of compression would form useful data specially if it ran through the long range of speed used on the road.
