For the Attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. Dear Mr. West, Further to our earlier correspondence, I am having sent to you under separate cover: (a) 12 sample aircraft plugs type X410, and (b) 11 sample aircraft plugs type X412. I am sorry that in the case of (b) we cannot today send you a complete set of twelve; this is because we have run short of screen tubes. I will send you this missing plug as soon as possible, and in the meantime I am hastening these plugs to you so that you can get on with your tests. As you will see, all the plugs are of the screened type and the gaps have been set at .012"/.015" in accordance with your letter of August 15th. I shall be interested to hear your experiences with these plugs, and remain, Yours faithfully, N.F. STOCKBRIDGE, Managing Director.
