| 16 JAN 1931 RECEIVED X.6031. To EFC from Sg.{Arthur F. Sidgreaves - MD} re Buzzer Type Horns. Sg{Arthur F. Sidgreaves - MD}14/E15.1.31 Referring to EFC1/AD2.1.31 we have now tried this latest type Bosch horn UK.12A. and, whilst it seems to be a little better than the former one tried, nevertheless I still feel that there is no real case for making a change to this type of horn from the Klaxon. Our views are still as per those expressed in Sg{Arthur F. Sidgreaves - MD}19/E.{Mr Elliott - Chief Engineer} 22.12.30, copy of which is attached. The horn is being returned to you when next a car comes up to Derby. X.6077/8 If the Experimental Dept. still feel that there is a good case for chahging from the Klaxon horn to the Buzzer type, I should be glad if they would bring the matter up for discussion the next time I am at Derby.
