Dear Sirs,

For the attention of Mr. E.{Mr Elliott - Chief Engineer} Fowler Clark.

We thank you for your letter of the 23rd. inst., Ref. EFC/T. regarding the performance of a particular Lucas E.R.6 Magneto with tungsten points.

Our experiments with tungsten points show that occasionally a good performance can be obtained but that the results are not consistent and that the average is much below that obtained with Iridio Platinum points.

It would be very useful to us to know the results given by this magneto on your leak test and if you could conveniently give us this information we should be greatly obliged.

Yours faithfully,

FOR AND ON BEHALF OF
NORTH & SONS, LTD.
