Regarding D.{John DeLooze - Company Secretary} 50232 and D.50294/5/8 and D.50306 it should be attempted to buy these pieces in Bakelite Micarta, if, however, this is found impracticable then D.{John DeLooze - Company Secretary} 50232, D.50298 and D.50306 should be bought in Mica and D.50294/5 in Micanite. We have already handed to EFC. a blue print of D.{John DeLooze - Company Secretary} 50301 Commutator Brush in order that he may order the qualities which he considers most desirable. The Terminal D.50302 would be produced here and sweated to the pig-tail here by us. Will Mr. Coverley kindly arrange to have a sample casting made with the metal shewn in red on the blue print cut away, this would greatly facilitate coring when producing this piece as a die casting and it is thought that it will not appreciably weaken the casting. Mr. Bailey would like to see this piece. BY/WER. W&R | ||
