We consider that this is a good opportunity for having this coil opened up for the purpose of examining the method of construction (see WB {Mr Brazier / Mr Bell} 109 attached to EFC {E. Fowler Clarke - Electrical Engineer} 2/T8-11-26) and also to discover the exact cause of the partial failure. Signed H.E.W. This Sheet must be filed on completion of the work. RR 236 (150 BKS.)
