| W/S. CWB. from Hs.{Lord Ernest Hives - Chair} X766 EAC. 'V' series. X8770 Hs{Lord Ernest Hives - Chair}10/LG10.6.25. We are sending 44-PK to London tomorrow. We are taking the opportunity when you have this car of fitting to it a louvred bonnet and sending with it a standard shuttered bonnet. BJ. has expressed a desire that Sales would like to try a 'V' series car comparing the louvred bonnet with the standard bonnet to note the difference in noise. We should therefore like this test to be made before the car is returned. We are also endeavouring to fix on to this car an improved silencer which should be more quiet.
