Messrs Rolls-Royce Ltd.,
D E R B Y.

Dear Sirs,

We thank you for yours of the 13th, and immediately the banjo fittings come to hand we will make tests on the complete plugs and give you a report. If we find that these plugs do not give their rated flow, we will take steps to make a test fitting to enable us to measure the rate of flow after the cartridge has been pressed into the studs.

We should like to confirm our conversation with Mr.Hancock and Mr.Gaye when we offered to supply a complete set of Luvax-Bijur fittings, as we think it would be well worth your while to consider whether the difficulties you have encountered are not partly due to the differences in design between the two systems; particularly in the matter of getting a high pressure in the pipe line and ensuring that no air can leak into the system.

On the subject of the most suitable pipe for the distribution of the oil, following our visit to your Works in January we wrote to Mr.Bijur asking him why he recommended the use of hard pipe, which is contrary to normal practice. We attach hereto a copy of his reply, from which you will see that they consider the soft piping to be the best for general purposes, only using the hard piping for flexible coils.

Yours faithfully,
for LUVAX LIMITED
H.W. Pitt.

Encl.
