The development of the letter code desk is described, particular reference being made to the necessity for the characteristics to be suited to the operating personnel. An explanation is given of the design features introduced as a result of this unit being required in relatively large numbers for this class of work. The development of the special printing unit for code application is described, with particular emphasis on the very high reliability required. An indication is given of probable future trends.
