Na{Mr Nadin}7/IB29514. Mr Haldenby's note on the above memo. Wor.{Arthur Wormald - General Works Manager} for Na.{Mr Nadin} 5. 6. 14. I do not think this horn would work satisfactorily. It would undoubtedly upset carburation. Also the horn would not blow with the throttle shut as the reed would stick. The circular says this in a roundabout way. I should say one would have to adjust the throttle to give the correct vacuum before the horn would blow satisfactorily. (Signed) T.S.H.
