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.

Number 5 in the latest release. This document is dated 26 November 1943 and is a tabulated summary of the Performance Differences to be found between the Wireless Set No. 9 Mk. I Canadian and the Wireless Set No. 9 Mk II Canadian.

I've been able to track three of them down. These are pre-war positions. F.T. Winter was the manager of the Maritimes region in Halifax. Jackson was the manager of the radio and appliance division and Bird was the Technical Liaison officer. I suspect the other two were in management as well.

Prior to the war Canadian Marconi had a lot invested in marine radio so Winter's experience with the marine crowd in Halifax was useful.

Thanks for that, Bruce. I find it interesting how the various parts of large corporations come together on major projects.

It's quite likely that the original chart was like the metal "Working Instructions" plates or instruction card, the same size as the manual, and would fit the storage compartment (possibly along with the Unit Record Log), but they later decided it would be more useful screwed to the wall (etc.) close to the aerial tuning unit for easy (and hands-free) reference.

Hi Chris.

It does get interesting when unknown little tidbits pop up about these sets in production. Makes me wonder just how dynamic the development and production of other sets might have been, like the No. 19 Set Mk III.

This file is also out of the 1943 Microfilm Reels, but the actual date of it is unknown.

It is a proposed draft for the COMPLETE STATION LIST for the Wireless Set No.9 MK II.

A lot of dark pages in this file, so I have had to split it into six packets to keep the file size within limits. I will do two back-to-back posts of three files each.

Although this report was filed on Sept. 14, 1944, you will note the evaluation itself was completed some time earlier in the year. It is also interesting that the Shipping Manifest Lists were included in the report. They appear at the end of the second packet.

CMC even provided a CMP Wireless Lorry for the evaluation and it would be interesting if that particular vehicle was found to still be alive and well today, somewhere in England. Also along that line, CMC also included the Serial Numbers of each piece of Wireless Equipment sent over for the evaluation. I wonder if any of them have survived today as well?
