| Hs{Lord Ernest Hives - Chair}/AJL. from EFC. x4477 EFCL/T28.3.29. BULBS FOR P.100 HEAD LAMPS. The four bulbs handed to you herewith have been obtained hurriedly from Messrs. Lucas. It is stated that these bulbs, which are produced by the G.E.C., are still somewhat in the experimental stage, as certain troubles have been experienced with the filaments. We are therefore anxious that these bulbs be specially watched and to receive from you reports of any unsatisfactory working. EFC. | ||
