Wanted: WS19 No3 control unit

[Russell Boaler]

Thanks Patrick.

It's to go in a British armoured car and I mainly want to avoid one with Russian text. Excuse my ignorance but I'm not sure what the differences are between the American and British versions. Here in NZ the sets with Russian text are generally known as "Canadian sets". It will sit in close proximity to the attached remote control unit so ideally something that has a similar finish.

Indeed, the units aren't light so postage from anywhere won't be cheap but that's life I guess.

That is a junction remote control number 1 in your picture, ebay has lots of Number 3 MK II on them from time to time. So you want the British version, gray with black lettering, the lend lease are usually a little different color, will look out for you.

Most of the ones with Cyrillic are lend lease models, that went to Canada, UK, Australia etc., just depends if/what you want your radio to be, all matching or piece meal. Here is a Number 3 MK II so others can know what it looks like.

Is this for the DAC? or another one, most of the Number 3 MK II were in Dingos.

That is indeed a picture of exactly the No.3 control box that I'm after.

It is to go in a Daimler Armoured Car as you suggested. Attached is a picture of the general WS19 radio arrangement in the back of the turret. I do have an old control box as shown in the picture and it has long since lost all its labels and is starting to suffer from some corrosion... hence the desire to locate one in better condition.

As this is a late production Mk2 DAC it has it has an external cable drum fitted which is wired back to the WS19 set via the Junction-remote control box shown in my earlier post. Most DAC's didn't have the remote control box fitted. I'm currently struggling to figure out the mounting position of the remote control box as there is simply no room for it beside variometer (it's physically the same size as the No3 control box).

Hi Russell,
The No.3 Control Units I have all have the English and Russian cyrillic letters on them, I believe these were largely made in the US by RCA for Lend Lease. As far as I know these boxes were made in the US as you rarely find them with some form of US manufacturers marks. The truly British made sets were made if I'm correct by Pye and are very distinct in their colour and markings. I wish you good luck in finding what you are looking for and keep checking ebay.co.uk for new listings.
Cheers,
Patrick

Your 19 set with the black text on white decals looks to be early Canadian or American made. Does the data plate on the front confirm this? British sets should have the face text in black right over the pale blue/grey face paint.

As for the mounting of the control unit. Are there blocks on the underside of the turret roof just forward of the set? Sometimes the units were bolted to the turret ceiling.

Thanks Bruce. Attached is a picture of the ID plate on the WS19 that I'm going to use. I'm no expert in WS19's (would barely even qualify as a novice I suspect) so am not sure if you can deduce the country of manufacture from it.

Here in NZ most of our defense force equipment used in WW2 was sourced from our Commonwealth friends an beyond. I've seen a variety of different WS19 sets (Mk's, colours etc) so presumably we took whatever we could get whenever we could get it. This isn't the original radio, that was gone well before I purchased the DAC, but a Mk2 WS19 is the correct radio for a Mk2 DAC.

There are no other fixing points on the turret for securing of the radio equipment. I suspect/believe that the remote control unit was mounted on a plate that was secured to the turret using the bolts associated with the radio armoured wiring outlet. I'm starting to think that the Variometer may have been re-positioned slightly on the later DAC's to create a bit of space....

Ooh! Aeronautical & General Instrument Company Ltd.

It's British (and the company is still operating, mostly as a Defence contractor, I think). They also made photographic equipment: Agiflex and Agifold cameras, Agiphot enlarger, etc.

Unless you use an extension cable on the droplead, I think you are going to have severe difficulty in mounting the control unit and Junction Remote Control close enough together - although the control unit was mounted flat on top of the set in the Daimler Dingo, so if there is room you might get both of them on there. The other problem is: where does the remote cable reel mount? If it's on the turret then you need a feed through the rotary base junction (if fitted), or to connect the JRC to a droplead when required for use - it also needs a 12V supply for the relay to work, and I think the green light may have to be visible to the wireless operator when in use.

Best regards,
Chris.

Second thoughts: it's a 'bitzer' and the ID plate is not original. Looking at the (mismatched) knobs (a mixture of UK and US types), the American key jack and acceptance stamp in the watch holder, it's probably an early Philco Mk.II set with an A.G.I. nameplate added.

Is there enough clearance to put the control unit on top of the set? That's the usual Daimler install - with the lampholder facing forwards so the operator can see it. If so, you need a mounting plate on top of the set that fits to four of the three hole sets on the case and is drilled for nuts & bolts to mount the control unit.

I'd also query the variometer position: on the Daimler scout car it was on the right hand side with aerial feeder No.4 through the hull, but in the armoured car it may be on the left (looking from the front) with the aerial bases on external brackets on the turret. (There was a D.A.C. in the IWM (London) a few years ago, but the only things I remember about it were that it had been moved into position under a balcony and the aerial rod had destroyed the base as a result, plus the 'B' set aerial base was a horrible mock-up made of conduit fittings and tinplate (about half the size of the genuine item).

Chris (possibly in rivet-counter mode at the time).

Yes, an amazing early British set from a very hard to find maker. Well done!!
