Wireless Set No. 52 Canadian - Project

[David Dunlop]

The other interesting discovery regarding the Coil Assemblies, RF, was that it was also considered a major sub- assembly of the Receiver by Canadian Marconi Company.

Along the top end of the left side mounting strip of the Coil Assembly another Production/ Control Number was found, as per the attached photo, this number shows as, ‘#6247’.

It is hard to see this number when looking at a fully occupied receiver chassis from the front because the mounting for the Band Switch gearbox blocks a direct view. Then factor in if one was not aware of the existence of this number, one would not be looking for it anyway.

So it seems that as far as the Wireless Set No, 52 Receiver is concerned, the receiver chassis, Crystal Calibrator chassis and the Coil Assemblies, RF chassis all had Control Numbers assigned to them during the production process.
