Barr and Stroud's Mark III series of step-by-step fire control instruments were a modest upgrade from the Mark II* series. As they and the Mark III* and Mark IV series are outlined in the Handbook of Fire Control Instruments, 1914 but not mentioned in the 1909 edition, Mark III probably was introduced between 1910 and 1912.
With the sole exception of the Single Range Receiver which was now customized for use reporting range cuts to the TS, the Mark III instruments differed from their predecessors only in their wiring interface. Whereas the Mark II housings each required 2 or 3 individual cables to enter, the Mark III devices consolidated their wiring to receive just a single multi-core cable through a gland. I presume that the outward appearance and function was otherwise identical to the earlier instruments.
