FROM DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} Copy to BY [text crossed out] [Handwritten Annotation]: WST see me [Handwritten Annotation]: X6032 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}2/M14.7.32. HORN MOUNTINGS. [STAMP: RECEIVED 18 JUL 32] We thank you for HS{Lord Ernest Hives - Chair}/WST2/MA12732. You have standardised the H.F. horn mounted on the front apron on P. 2. and 25HP. You now report that the same horn mounted on an apron which is almost exactly identical on J.{Mr Johnson W.M.} 3. and Peregrine produces a very bad sound inside a closed body. We fail to understand this. It must mean either that this phenomenon occurs on P. 2. and 25HP. and has passed un-noticed, or that the aprons on J.{Mr Johnson W.M.} 3. and Peregrine are not exact copies of those on 25HP. as was intended. We suggest that you should further investigate this before you definitely state that the horn cannot be mounted on the apron. [Handwritten section] If by any chance the scheme standardised on P.2. + 25HP. does not consist of a horn on the apron, we are not aware of it. DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} Again what has been done on P.II. + 25HP. can be reproduced on J.III + Per. S. A report on these matters would be welcomed [Signature] 15/7/32. | ||
