Default Robbins & Myers Co. Ltd

The Canadian Division of this company had the contract from Canadian Marconi for production of the two Rotary Transformers used for HT1 and HT2 Outputs from the Supply Unit. They may also have been working together with similar work for the No. 9 Set and No. 9 Mk I Cdn, but I do not know for certain.

It is now hard to find much information about the manufacturing side of this Canadian operation. I think their plant might have been located in Branford, Ontario, or close by. Does anyone in the area recall the plant and where it was situated and when it closed?

Default Newspaper reports

You could try searching archived newspapers for that area. These often include small local reports of 'significant ' happenings at local businesses, such as closures, changes of management, and so on. I have not used the Canadian archival system, but there is one online:

The Australian 'Trove' system has been very useful in my research, hence the suggestion the Canadian system may be of help to you.

to see if they are helpful. My impression is that they were makers of electric motors and devices and ceased operation (as Etatech) in 1987

Well this all proved to be an interesting trip down Memory Lane. Thank you all for your posts.

Robbins & Myers were certainly an amazing company and they seem to have had a long connection with Marconi, right back to Mr. Marconi himself, so the fact they built the Rotary Transformers used in the Wireless Set No. 52, is now no great surprise.

It was also nice to learn that their original wartime factory in Brantford, was still standing a few years ago.

On the sad side, however, nothing remains of the company now as far as any possible central archive source is concerned, but a number of sites on the web are trying very hard to reconstruct relevant information. The company did maintain an office in Calgary serving the petroleum industry but as of a few years ago, that office was down to just 3 employees and are now no longer listed. But their household fan division is still alive and well under the Hunter name.

Oh well. Thanks for the help everyone. Best hope the brushes in the two Rotary Transformers are all present and in good shape.

David
