| X6074 WST See me S/W To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} re Electric Horns. Hs{Lord Ernest Hives - Chair} Sg{Arthur F. Sidgreaves - MD}8/E22.3.32 X6032 I have been using a Lucas Alto horn on 58-GN for some time but have recently had a Klaxon High Frequency horn fitted of the same shape and type as the Lucas Alto. I like it better than the Lucas Alto. It has a better note and seems to be very good from a road clearing point of view. I should be glad if you would arrange to have one fitted on 19-EX before it goes on its 10,000 miles test as, if we are going to give up the Klaxon motor type of horn, I think that this Klaxon is more suitable than the Lucas Alto. The Klaxon horn I am referring to is not yet in their catalogue but they say that its correct designation is: Type HF{H. W. Frost - Coachwork Inspector}5 - with bracket HFS/23. Sg.{Arthur F.
