| COPY. S/W. (BY) Copy to Sn.{Mr Sanderson} ----------- Bs{A J. Barnes - Assistant Manager}2/M/1.10.28. re 20 HP. HEADLAMPS. -------------------- BY/Cgh{W Clough}13/N19.9.28. Can you please give us any idea as to when we are likely to have your report on the Lucas R.160.S. type headlamps which at our request, are being tested by the Experimental Department ? Messrs. Lucas are pressing us to adopt this lamp as standard equipment to the 20 HP. chassis, but naturally we cannot take this step until you are able to confirm to us that they are at least equal in lighting efficiency to the lamps now being fitted by us as standard.
