Wireless Set No. 52 Canadian - Project

[David Dunlop]

I was able to re-plate the mounting screw and lock washer last evening so this assembly is now ready for re-installation on the Sender.

While the Handles No. 72 and 80 continue curing, I decided to move ahead to getting the three switch knobs along the lower portion of the Sender front panel cleaned up and ready to go.

These are all the above noted KNOBS, Phenolic, Pointer No. C1 and this is turning out to be great practice, as there are 5 each of these same knobs also on the Receiver panels and I now want to go back and restore their luminous marker slots.

The attached photos show the original condition of the knobs, what they look like cleaned up and lastly with the base coat of flat white paint applied to the marker slots.

Tomorrow, I shall fill in the marker slots with a new layer of Neutral Luminous Green paint.

Great work Dave. I only hope when you are all done and need to give it that final authentic 'patina' you can find a room full of chain smokers to blow tobacco smoke at it!!

[David Dunlop]

Indeed, Bruce! That could be a real challenge these days.

I possible backup plan, however, would be to find a Blacksmith's Shop where I can place the set beside the forge for a few months.

I was able to infill the marker slots on the three knobs with Neutral Luminous Green paint this morning.

Once they have dried for 24 hours I can put the knobs away until needed.

Two NOS pairs of these cables arrived in this morning's Mail.

These are the interconnecting cables between the two 6 Volt Wireless Batteries that sets them up in series to provide the 12Volts DC needed for the wireless set.

One pair of these cables was issued with the basic Wireless Set No. 52 and served as the working set for the wireless. The second set was issued with the Remote Receiver Kit and when not in use, were stored in the Case Operating for the Remote Receiver.

There is an interesting production history with these cables. The ID collars on two of them have three lines of information in large font as follows:

CONNECTOR,
SINGLE #3
CMC 110-317

The other two cable ID collars read in four lines in a smaller font:

CONNECTOR,
SINGLE No. C3
CMC 110-317
ZA/C 2270

I am assuming the second set is a later production run from Marconi than the first set.

The slotted copper lugs on each end have been zinc plated and stamped on one side with:

S-90-A

Often when you see a "C" in front of a number it is a 29 set part.
