I understand the recent experiments on dynamo brushes having a greater angle on the spring pad are likely to be standardised, therefore, before the Morganite Company make moulds, would it not be advisable to delay a short time, to enable the mould which they will make, to be to our latest requirements. Perhaps you can tell us whether the standardisation of this new angle is likely to be in the near future, or at some distant date. BY/RD. | ||
