Wireless Set No 52 Canadian Production

[David Dunlop]

This is the fourth document of the recent batch assembled by Jacques Fortin. It is identified as MEMORANDUM No. 8 and dated 27 October 1943.

At the very beginning, this memorandum lists five members of Canadian Marconi Company in attendance at the relevant meeting concerning the Wireless Set No. 9 Mk II Cdn. No titles provided but if anyone can identify who they were, it would be really interesting to find out who was actually there from CMC.

The other tidbit can be found in the MECHANICAL DETAIL Section of the memo. There, it states that a small compartment will be fitted to the top of the Carrier to accommodate the Instruction Manual and Tuning Chart.

This is the first time I have ever heard of the small metal chart being included here. I went and found mine to try it out. Width is perfect, but length if one half inch too long. this one has the 12 holes punched around the perimeter of it for mounting in a location close at hand to the wireless set. If the holes were not punched in it, it appears it could be shortened enough to fit the compartment.

As usual, you find a new bit of information, and more questions pop up. Was there an earlier version of the metal tuning chart with no holes that fit into the compartment with the manual? Did the manual originally not have a foldout tuning chart inside it? Given the set came with a rain cover for the front of the Carrier, there is a certain logic to having a metal chart to avoid getting the manual wet needlessly.Did they switch to a slightly longer metal chart to allow it to be readily mounted? Interesting mystery.
