WST Rolls-Royce Limited, Derby, England. Attention: Mr. H. {Arthur M. Hanbury - Head Complaints} E. {Mr Elliott - Chief Engineer} West, Reference - Hs {Lord Ernest Hives - Chair} /Wst.9/Ma. Gentlemen: We have your letter of May 7 concerning a magne-to electric tachometer, type 70-05. To prevent a misunderstanding, we wish to point out that the instrument is a magnetic tachometer driven by a flexible drive shaft from the engine. It has occasionally been construed as an electrical instrument. We are at present re-designing the tachometer to improve its performance, and prefer to wait to send you data when our tests have been completed. The price will be in the neighborhood of $30.00 each. Thank you for your interest. Very truly yours, KOLLSMAN INSTRUMENT COMPANY, Inc. G. {Mr Griffiths - Chief Accountant / Mr Gnapp} R. {Sir Henry Royce} Adolph GRA.hs {Lord Ernest Hives - Chair} | ||
