| N-W. EFC. X2894 All/H.4.7.30. Technical - re Tungsten Contact Points ---------- I am very sorry that I have not replied earlier to EFC1/AD.19.6.30. I have, however, had to put the matter to Br.{T. E. Bellringer - Repair Manager} and have only been able to get a final settlement this morning. When cases of quick burning do arise, we will in future make a careful note of everything which has any bearing on it, and will let you have a full report. A.{Mr Adams} SGE | ||
