1944 C-15A-Wire-5 Restoration

[Robert Bergeron]

Now the paint and the masonite for the shelves .

[Robert Bergeron]

Here i am playing with Masonite for the shelves . Q : White side up or down or in other words the brown side up ? How about the one facing forward acting as a door to the lowest compartment ? In aviation we say : Keep the blue side up and the brown side down ..

Brown side up (sorry pilots) and not painted white if the HUW is any indication. The outside face of the lower vertical (is it not sheet metal?) appears white in original surviving examples.

[Robert Bergeron]

Some of the equipment .

[Robert Bergeron]

Thanks Bruce . Rodger that for the lower door panel , white . Metal and not Masonite ? Gord Falk seemed to have a different opinion . Pictures, memories ?

Looking at your diagram, I would guess that the brackets hook to the front and rear of the wooden carrier in some way and are spaced left-to-right so the carrier can't slide around. This suggests that there has to be some way to release at least one of the hooks (likely a front hook) to get the hooks around the carrier. I don't have one to study so can't help more than that... photos will be welcomed if you do find one to work from.


Looking at the diagrams, the radio, power supply and antenna tuner all look to be a later generation than WS19. I don't know whether the carriers remained the same or changed with the generations of radio.

Those are the post-WW2 mountings for Carrier No.25 with Barry mounts instead of the 'bridge type' shock absorbers. (The set shown is a C12 and the front clamps are wound in and out by a slotted screw below the hook.)

The wartime ones were mostly made from sheet metal. (I have a spare one somewhere (hoping to find a partner for it eventually), and will see if I can find it for measurements, etc.)

[Robert Bergeron]

First item in the list .

[Robert Bergeron]

Bolts through the wireless table .

[Bruce Parker (RIP)]

Robert, what is this for, the 19 Mk.III set under the amplifier? If so you need a carrier No.1 (or 21) which is a metal rack with four angles to hold the 19 set and the supply unit (last pic). This carrier has four rubber feet screwed to it to attach it to the table.

The No.23 carrier is the wooden board type with notches in each corner. You need a pair of No.1 carriers (see pics) screwed to the table and these become the quick release mechanisms that clip into those notches on the wooden board. I don't think a 19 set configured this way would fit under the amplifier.

[Robert Bergeron]

Bruce , that is what i am looking for exactly . The Amplifier set up i am going to use on static display at home . When traveling to meets i am going to go light and have the simpler set up with just a No 19 on the wooden carrier . I need to slide it in and out of the table and box to show it outside to the public . So yes , you nailed it . I will write privately . Thanks .

[Chris Suslowicz]

Yes, those are the original ZA.10316 Carriers, Mounting.

I think they should also have some metal plates with matching holes to prevent the shock absorbers (bridge type) from spreading under the weight of the set.

I have a wrapped example and will try to find it later today. The plates will be easy to make, just a strip with four bolt holes to match the shock absorbers.

(There was another version with more shock mounts (fitted inverted?) for the "stacked" British WS19HP, along with a bracket and mount to clamp the RF amplifier to the wall of the wireless body to prevent the assembly rocking under acceleration/braking that could damage the shock mounts.)

[Bruce Parker (RIP)]

Yes, four strips for both top and bottom of the table. I have them just not in the pic.

Out of interest, does anyone know where Z1/ZA.10320 Connector, Single, No.33 is used in the Truck and Ground Station? It's on the kit list, and has a slotted lug terminal at one end, and a 2BA? knurled terminal at the other. 3 feet long, and the illustration in FZ256/3 has the caption swapped with No.191 which is entirely different (and probably a grounding lead for something entirely different).

(I got one recently and it fills a gap in the Truck & Ground Station kit.)

Chris.

[Jordan Baker]

Here you go Chris. It’s in the manual for the truck/ground station. Diagram on page 9,

[super dave]

Just catching up on your thread, So for the shelf you still have to add the footman loops and the straps to hold all the items from falling off while driving.

D'oh! That should have been obvious as I have a later British version with (I think) a double-ended terminal (which may allow for two counterpoises or one and an earth pin) on the end.

Thanks.

Chris.

[Robert Bergeron]

Thank you Chris, Bruce & Jordan . SUPER DAVE : Yes , i need 8 large Footman loops to complete the shelves and they are on order . I have the canvas straps .

[Robert Bergeron]

Shelves primed

[Robert Bergeron]

and painted

[Robert Bergeron]

Installed the shelving cabinet .

[Robert Bergeron]

I have this loudspeaker . What is it for ?

[Robert Bergeron]

Dated 1944 C Broad Arrow marked . Pocket watch holder . It will make a great loudspeaker for the No 19 set . No more uncomfortable hearphones !

AR-88?

You should be able to drive it from the WS19, but may need a transformer and a volume control, depending on the impedance (and to avoid feedback from sidetone if it's too loud on transmit)!

Our common friend and contributor par excellence David Dunlop had asked the question back in 2017 : How do you know where to drill the holes in the table top to install the different radio carriers ? A : A Masonite board came screwed to the top with all the possible holes pre-drilled to accomodate the different carriers . No written instructions in the installation manual . The Masonite acts as a mask or template . Much better than words ! I recently acquired this original table from another unit that was located in New Brunswick but that came from Ontario originally . The Masonite is in good enough condition to reuse it . Underneath is a perfectly sound 3/4 inch plywood . Voilà ! Mystery solved.

[Robert Bergeron]

No joke , this is a long standing mystery that is now solved .

[Robert Bergeron]

These are the rubber supports made by our friend and contributor Jordan Baker . I have made steel strips to prevent them from spreading under the weight of the 95 + Lbs of the No 23 carrier and the WS No 19 . I will use 2*inch bolts . When i get the mountings , carrier No 1 i will update the installation . I can’t wait for the postman to come by with them !

And they will arrive with four original metal strips, two for the table top and two for the bottom.

Posts 592/593 is a VERY hard to find RCA AR88 Loudspeaker. It is only rated at 2.5 Ohms. This was a late production run for Canadian and British Contracts as it had the Pocket Watch Holder predrilled and capped off so one could be added if needed. Earlier versions lacked that feature. The AR88 Series of receivers were a very highly regarded Intelligence Gathering piece of kit still in use in remote northern areas of Canada well into the Cold War Era.

You would be better off sticking with the Gunnery Speaker designed for the 19-Set/Tannoy System.

That masonite sheet needs to be preserved (and documented) for posterity!

I wonder if anyone has a plan or map scanner big enough to produce a 1:1 copy on paper? (Then you just need to work out which holes correspond to which set carrier!)
