| Roy.{Sir Henry Royce} from EFC. X6089 EFC2/AD3.1.31. X.6089. LAMP BULBS. The S.7214 bulbs which we received as replacement bulbs to 7 S.7168 bulbs which you returned for us to our EFC3/AD3.1.31 we find to be satisfactory and more suitable than those returned. We should be pleased if you will advise the G.E.Co. accordingly and at the same time obtain for us two copies of their up-to-date lists of Osram lamps including particularly the complete range of automobile lamp bulbs.
