J.{Mr Johnson W.M.} BARTLETT. DUNSTABLE BEDFORDSHIRE OUR REF. NFS/GEB. YOUR REF. 18th April, 1936. Messrs. Rolls-Royce Limited, Derby. For the Attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. Dear Mr. West, Further to my letter dated the 9th instant, sending you some sample detachable type plugs with sinterkorund insulators, and to my further letter of the 14th, warning you of the troubles we have encountered in our own tests on these detachable type plugs in the matter of "blowing", I want to tell you that I am so disturbed that this blowing difficulty may upset the performance of these plugs, that we have decided to make up for you immediately some further sample plugs with the same heat characteristics, but of the non detachable type, which should entirely eliminate the risk of blowing. We hope to have these plugs available in about ten days' time, i.e., about April 29th, and as soon as they are ready I will ensure that they are mailed to you immediately. Yours faithfully, N.F.
