I think you are right on the money. I found 2 diagrams in loco cycl. 1922 that illustrate it. It is even mentioning as you said that it should be mounted "in place of moderate warmth." I posted temporally the 2 diagrams for those who are interested. See: http://www3.sympatico.ca/sparent2/question/airsignal1.jpg and http://www3.sympatico.ca/sparent2/question/airsignal3.JPG Obviously, CN machinist never bothered changing the location of this device on 923. I don't have a engineer side when numbered 93 so I don't know if was eventually changed. Maybe someone could confirm that.

Note that it is located near the outlet of the main reservoir. I have a book titled (Up to Date) Air Brake Catechism, by Robert H. Blackall, October, 1898. I suspect it is an air reduction valve, to maintain air pressure in the Train Air-Signal System at 45 P.S.I. It is stated that: It was formerly customary to locate them [reducing valves] outside, next to the main reservoir, but now [1898] good practice locates them inside the cab where they cannot freeze in winter. The signal walve and whistle were usually located inside the cab, under the engineer's or fireman's seat. The whistle signal was used on passenger trains by the conductor, to communicate with the engineer. Brian D.
