| WST X6032 To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} Copy to Hn.{F. C. Honeyman - Retail orders} re Electric Horns. Sg{Arthur F. Sidgreaves - MD}17/E4.4.32 Thanks for Hs{Lord Ernest Hives - Chair}/Wst.17/MA.23.3.32 and for sending me one of the latest Lucas HF{H. W. Frost - Coachwork Inspector}722 type horns. I have had it fitted to the car. It certainly is a great improvement on the other Lucas Alto horn and is a better job, I think, from our point of view, tham the Klaxon horn type HF{H. W. Frost - Coachwork Inspector}-5. As we are really trying to arrive at something to supersede the Klaxon, it rather looks as if you ought to have one of these Lucas horns fitted to 19-EX before it goes on the 10,000 miles test. Perhaps you could take the opportunity of fitting the Klaxon HF{H. W. Frost - Coachwork Inspector}-5 as well. Sg.{Arthur F. Sidgreaves - MD} | ||
