Some sort of rubber/neoprene. Ron

11 set for sale
 

Here's one for you guys across the pond. It'll be interesting to see what it goes for.

In Malta. I'll watch with interest but wont be bidding. Ron

my radio knowledge is zip, however The star in firearms and carriers refers to Canadian design or at least I thought so until recently.
I'm not sure what model or mark you describe the Canadian carrier mount as, Chris, but the prefix of the Ford part number CO1UC 105046 means:
C= Canadian design
0= 1940
1=85 horse power
U.C.= Universal Carrier.
I think the star designates a Canadian design in this mount. I have all of it as original except the big rubber boot. Quite a few copies have made it to the U.K. as a result of my bits.
I havent been able to follow or absorb you description, but that is probably me.

No bids on that British set in Malta.....I would have thought it would sell for that amount? Ron

The 'star' isn't Canadian. It's just a British/Commonwealth way of indicating a design change in a piece of military gear that isn't significant enough to warrant a new 'mark'.

11 set on the air
 

A no. 11 set has been on the air recently. A friend of mine Clem, grew up playing with and fixing old wireless sets he had salvaged from the local tip. He did a PMG radio tech course in the 1960's and eventually he worked at the Telecom research labs in Clayton.

I gave him this 11 set years ago, its been played around with and its now back on the air in somewhat modified form.

The one in Malta is re-listed with 50 Quid off.

That set appears to have hand scribed panel lettering.Most unusual. Was it originally made like that ?
And it's not made by EK Cole either.

I’ve been emailing the seller. He has painted it on himself in an attempted restoration, he should of left it all well alone, shame. Might of been worth a punt in original paint. :doh:

What's with this Control Unit A for the 11 set? I've never seen one with this rotary unit. And it's made in the USA!
Or did somebody just mount the transformer in the Control Unit case?

Your second suggestion is correct.

It's a US made dynamotor from a WS19 supply unit fitted in the eviscerated remains of a remote control unit.:ergh:

Parts only, and only if the dynamotor works.

Chris.

Here's another ebay item. It says for 18 set or 19 set but it's dated 1940. It's a military ohm meter for testing batteries I think.

Oh good grief. £45, really? You can get them for under £5 at radio rallies, usually.

Instrument, Testing, No.1 is a very basic test meter for line telephony and telegraphy use, back in the 1940s. It coexisted (and eventually replaced) the "Detector Q & I" magnetized needle voltage and current detector used on early telegraphy circuits (that was still being manufactured and issued late in WW2).

Q id Quantity (current, I think) and I is Intensity (Voltage), but I may have them backwards.

Anyway; Instrument, Testing No.1 allows voltage and current measurements on field telephone circuits, on-load testing of 'S' and 'X' cells to determine their usability, and approximate low-ish resistance measurements.

For higher voltages (wireless sets) there was the Voltmeter, Pocket, No.2.

There were a couple of less crude and fairly effective military multimeters, plus commercial equipment for higher echelons, and for accurate resistance measurement there was the trusty Post Office Box and a galvanometer, plus dry cell(s) to suit.

Chris.
p.s. there are a couple of others on eBay for less than a quarter of that price, and it's still too much (really) for what they are. (IMAO, YMMV)

There's a Control Unit A on UK ebay. It's a 1939 date with the serial # over 11000. That seems kind of high for the date. How many would have been produced for the No 1 set? Judging by the last pic the serial numbers weren't consecutive. I guess different companies got blocks of numbers assigned to them.

I got another NOS control unit A off Oz ebay It came with the strap and pouch and a mouthpiece. The other ancillaries were missing though. Would anyone have one of those connector pieces with the two screws?
The seller said the pouch was for the microphone but oh well! He was probably looking at it upside down! Built 1941 serial # 17506 as in the above post.

bits
 

Can you be more specific about what you need ? if its the strange shaped bit on the end of the lead , I've never seen one before . Those control units turn up at junk markets and swap meets here, there must be many of them still in dusty sheds. and garages

That's the one all right Mike. I ordered some bakelite in case I can't find one!
It slips over the two Control or Exchange posts on the remote then the reel of wire hooks onto the connector and goes to the other remote.

Accumulators
 

Those dry cell accumulators never seem to show up and there's not much info on them. I'd like to make some cases to go with my 11 set. Pic 1 shows 2 HT batteries behind the set. Using the set for dimensions I came up with the case being 10" high, 13 " wide and 3.5" thick and made of wood. You can see the grain. The red highlite shows a seam an inch in that will be where the cover comes off to replace the cells. It's held in place by those screws you can see. In pic 2 you can see that the screws aren't flush with the wood. Pic 4 shows the back side and there are no screws.
In pic 3 the strap attaches about 1" down from the top then that black rectangle is where the wires plug in. It's 1.5" by 3" and my plug is 1" by 2" so that's about right.
In pic 5 the highlited area looks like one of these batteries with the cover removed?
Does anybody have anything they can add? Pics would be nice!

Boxes
 

Good luck with that !

That would make another interesting project Dave."BOXES PRIMARY BATTERY 240 VOLTS" They would nicely fill up the space behind my set. Timber would be easier, but to my mind they look like steel?? The holding frames are simple enough (I have another vague picture of the frames also) Ron

The HT battery was basically the same as the one used by the No 1 set and it looks like it was made of wood. The LT was like the light version used by the No 1 set. Trucks carried two of each. The dimensions are given here.

I'm getting closer!
Here's the same looking battery box as used on the 18 set.
As I thought it's made of wood probably to eliminate the shock hazard.
The cells are wired differently for different voltage.
The Aussie 11 set manual doesn't even mention these batteries.

Bloody good research Dave!

So the way they are stowed behind the set, the dimensions are 15 5/8" (or is it 3/8?) long x 11 1/4" high x 3 3/4" wide.

The screw pattern for the lid of the 18 set box can be seen also by the notches in the case in the line drawing. ie 4 along the top and bottom, 2 down the right hand side and just 1 in the middle on the left. I wonder if the 11 set screws would be the same? Ron

In one of the pictures you can see 4 along the top and the two down the right side and another picture there's the 4 along the bottom so they should be the same. The 18 set box's dimensions are 14 1/2 by 11 1/2 by 4. You get 2 of them with 1/2" space between them for the mounting bolt and that's 29". The 11 set and the 2 power supply units are about 28 1/2" plus the ends of the mounting carrier so that's right.
And here's some hardware to hold the carrying straps.
Now to figure out the LT unit I guess.

So you would go with the dimensions of the 18 set boxes which does look right.

I was confused with the measurements in Table 1 Page 3 which I thought was from an 11 set book.

I've been trolling through my 1939 11 set "signals Training" Pamphlet No 19 Vol 3 but can see no exact measurements. Have you got this one? It's 95 pages plus a load of plates. I can email you a PDF copy if you want it. I also have the Ozzy version from 1943. Ron

The 18 set dimensions are right. The other ones are for the 1 set and the text said that box is similar to the 11 set one.
Use inch hardwood for the sides and good 1/4" plywood for the top and bottom. Cut the sides at a 45' angle but don't worry about how they cut it back between the screw holes.
When finished and installed on your truck they'd make a good place to store stuff that you don't want anybody to find!
Do you have a picture of the angle iron thing that holds them in place?

Apart from the line drawing in post 531. This is all I have. Cheers Ron
PS I've no idea why they're not produced as thumbnail pictures, so just click on the attachment if they don't appear.

Ron, are you proposing to make battery boxes?

If it's any help I have two bottom sections of the 18-set battery boxes available. They are completely gutted and missing the lids because a previous owner got a lot of them as surplus, fitted knobs to the side, and used them for parts drawers.

You'd need to fill extra holes, blank off the 5-pin socket and work out how to fit the WS11 socket to the shell. The internal dividers were wooden. It's the same shell as the WS1 (and 11) battery box because someone had a WS18 box fitted with the earlier lid (which had the designation moulded into it.

They will need a good clean and polish, plus reproduction of the strap fixings, etc.

Let me know if this is useful.

(I have a WS48 battery box which will do for the WS18, and it's unlikely that I would get the bits to resurrect either of these units.)

Chris.

That would be fantastic Chris. Are you still with the same email address? I'll Give you a shout. Best regards Ron
