X - extra print for Mr Brock. The remainder of the details on the L.O.P. have previously been issued. We do not propose building any more switches with aluminium bases and covers as we understand that the die for the base, which was put into the works for production is nearly completed and can be completed and used for further experimental work. The Armature Contact Platform and Clamping Plate D.71090/1/2 - are suitable for use with the latest contacts (solid shanks) but the Armatures etc, you have already made and the contacts D.71093/4/5 should be used up first, D.71093/4/5 being new members for the hollow riveted type contacts of which we have about 100 sets and are too valuable to scrap. Although we have sent you prints of D.71014 - Cover, we suggest that the putting in hand of the dies be postponed until the wooden (Cont'd). | ||
