| To BY/RD. from EFC. X4105D EFE5/T22.4.25. X.4105D - RR. CUTOUT WITH MODIFIED CONTACT POINT SUPPORTS - TYPE D.{John DeLooze - Company Secretary} X.4106. CUTOUT PROVIDED WITH PAIR OF CONTACTS MAKING CONTACT IN "OFF" POSITION FOR OPERATION OF RED LIGHT. Confirming our conversation, will you kindly instruct up experimentally under their respective X. Nos. modifications to two standard distribution box cutouts, providing in each case both for your type of modification of the cutout contact point supports (which we call D type) together with the auxiliary contacts making contact in the "off" position of the cutout. As you point out, these two modifications can readily be done at the same time on the same instruments and the respective natures of the two experiments will not interfere with one another.
