| Contd. -2- EFC2/T23.9.25. take place perfectly; the material of the moulded piece being therefore dielectrically and mechanically unsound. Redmanol coil cases could be made here at a much less cost than the stabalite ones which are bought out and machined here. In addition the finish of redmanol coils is unquestionably better. If these further coils give no suspicion of trouble it should be a proof of consistency of material. EFC. | ||
