C3/H11412 DEPARTMENTAL MEMO. This column is for Name of Person addressed. S to W. DATE. 11.4.12. Re Road-clearing Horns. With reference to the attached memo. from Mr. Johnson, we are using the Klaxon on most of our Trials cars, but as Mr. Johnson says, the note is rather unpleasant. Concerning the third paragraph of Mr. Johnson's memo., Mr. Johnson is evidently referring to the "Autovox" horn, driven by friction from the fly wheel. Would you like us to get you a few Horns of various devices to try, so that you may report fully upon this matter. W. Cowen.
