Warner socket
Identify the earth one, opposite that is tail. Clockwise of earth it is brake & anticlockwise of earth is convoy
-
Pleased to see it drives well
-
Yes it is. Somewhere I have some pictures with the full kit inside. This is not just teeth but maxilla-facial injuries.
-
Shan the only mods I did to mine was to remove the gun rack as I have no interest in guns & to remove the FFR "Dexion" racking. That meant I could climb from the cab to the rear, very handy when its raining. When I sold it I just put it back again.
A worthwhile mod was to fit a fluorescent penthouse light to the roll bar front & rear. You cannot use the clamps provided that are designed to fit the poles on tentage even if you file them they will not clamp properly. What I did was to use a U shaped exhaust clamp & fit one at each end of the penthouse light.

Some sellers like to peddle these as winterisation or arctic kits which is nonsense. They would be pretty ineffective for that, the thin foam is just to give some support to the aluminium covering.
They were only to be fitted to FFR vehicles for RF radiation protection purposes. Although I admit they are also quite handy for reducing condensation & giving a more cosy feel to the inside.
Kits for the 90 are out there but extremely rare at the moment. I fitted the 110 kit to my 90. The front piece is the same, but you need to omit the middle section as the rear section has the straps. You will find rear section will have quite a few gaps but will do until the proper thing turns up. With my middle section I cut it up & made blackout pieces to go inside the windscreen & side door windows.

Probably worth asking on here (don't be put off by name!):
-
As the makers serial number starts "BT", then it is a fair assumption that this was made by Brockhouse Trailers.
So Richard are you saying it came from the Far East or the RAF? Oh dear sorry wrong thread
-
Made by both Brockhouse & Sankey.
The small brass sign is an unladen centre of gravity marker.
PS As for price a lot depends on the state of the tyres. I have a similar trailer but with a cipher office 8 years or so ago it cost £450 to get 2 tyres fitted. So factor that in your offer, the treads were fine but cracking was the worry.

Well I have two vehicles given these ERMs 27BT68 & 27BT95 these were previously civilian registered.
I have the official chapter & verse of the BT allocation that I'll scan when I can find it. I think that other document is probably based on observations of the Fleet Transport Data Society.
-
I thought it best to scan it Tony so you could see for yourself. I'm dyslexic & didn't lose anything in the translation. Didn't want you to end up with a locker for the wrong side!

Tony I have got the parts book 2320-H-104-711
Trouble is that it is on fiche & my fiche reader won't light up, so bear with me.

CLIVE FV 1601 is a AUSTIN k 9 is it not
Nope Wally normally Humber 1 Ton, but the Australian Humbers had contract plates marked Commer. Although they still got referred to as Humbers!
-
As an aside I see in the manual for the Commer FV1601 used by the Australians that the B60 is black with just Sky Blue (I assume) for the generator & filter box.
-
Thank you for sharing those.
They look much more real than the images we are used to seeing with the newsprint type image in War Illustrated etc.
That prickly truncheon looks quite sobering.
-
-
I think you are correct Simon the earlier the literature be it UHB or EMER on B Series engines the more likely they are to be black & then with overhaul, repair or preservation the Sky Blue creeps in.
-
There are pictures around of airfield Rovers that did tow trailers with missiles to fit. Or perhaps this was just to carry the chaps to fit the missiles given that there are windows for passenger benefit I assume.
The window on the near side of course was particularly useful at otherwise blind junctions. The greatest annoyance (apart from "nice Jeep" & "nice Sankey (from those who assume all trailers were made by Sankey) was "pity you fitted the side windows & destroyed the originality" - That was where the contract plate got a good airing :-D
-
Nick confirmation indeed C2TS4 and the BTH logo :-D
Are you going to try it out? One N.Ireland veteran I was talking to described how he was stood near his vehicle & he hadn't realised the thing had been turned on. The end of his rifle touched the vehicle he heard a hell of a crack & he felt a hell of a shock. Later he noticed a small arc weld mark on the end of his rifle.
So rubber boots & non-sweaty hands then!

The booster coil predates Centurion as it was fitted to the wartime Meteor engine tanks so maybe why it never had a FV number.
That would explain that Richard I nothing about tanks.
In the days when it was very difficult to buy ex-MOD armour. I know when the first Ferrets came into the UK they were ex-Hong Kong Police & they were fitted with electrification. The earthing chain was fitted to the readily available drain plug. Are there drain plugs in Saracens & do they match in with the positions that Andy & Nick have observed?
-
Andy it is indeed an ignition booster coil. It seemed to lend itself well to vehicle electrification projects. You can see an identical one fitted to this Rover.
The part is identified as LV6MT8/2920-99-806-4049 cross relating it to VAOS it comes up as LV6MT8/THC2TS4
So Nick can you see the maker's part number on it ie C2TS4?
It seems not to have had a FV number as I assume it was an off the shelf component. The maker was not Lucas but British Thompson Houston Ltd
The booster coil delivers 13kV how this is felt on the human body all depends on surface resistance of the skin (sweaty or dry) and the footwear (damp leather soled shoes or rubber boots). So in a wet environment going over these puddles the standing on the ground the touching the vehicle could be fatal.
13kV may not be fatal as such but the current that flows is the significant factor, which of course depends on the resistance presented. Vehicles Branch Technical Group REME produced these figures. So depending on load resistance the current in milliamps (one thousandth of an amp)
1-8 Perceptible shock
8-15 Painful
20-50 Respiratory inhibition
100-200 Ventricular fibrillation
200 Severe burns
Descriptions of the workings of the booster coil remain elusive. It clearly is not a simple transformer as you cannot “transform” DC. The alternative electrification system used a normal ignition coil switched by a vibrator of the type that was widely used in WW2 radios.
The booster coil is quoted as having a turns ratio of 250:10,000 it must have some switching/pulsing system to drive it. It must be electromechanical; I have not idea if it is a rotary system or a relay switching. I suspect it is the later.
I would envisage that this is an autotransformer such that the 250 (primary) winding is in series (& in phase) with the 10,000 turns of the secondary but with the primary energising relay contacts. So that on switch on the circuit is completed the iron core within these windings builds up magnetism, in so doing the relay contacts open so that the magnetic field collapses & 13kV flows out of the secondary.
Once this happens the relay contacts close again switching the thing on & charging up & so on. From my own experiments with a coil testing machine working on a similar principle the load presented has an effect with impedance (there are all the inductive effects & the capacitive effects of load plus the basic resistive load) this is all reflected back into the coil so that the load will change the frequency so that the relay buzz become more obviously audible.
It’s a pity you aren’t closer Andy as it would be fun to take some measurements. Ah well there is always W&P.:-D
Incidentally the idea of using a Centurion booster coil in this way I believe was first tried in Palestine by the EME of an Airborne Workshop who explained to me how he dreamt up the idea.

Hi,
I have one in my Mk6 Saracen and also Saladin. It is NOT, I repeat not for giving electric shocks.
It dose give out a high voltage though. Its conected via a HT cable though the hull to a chain on a
bracket. When wading, it sounds a buzzer when you get to the maximum depth you can go without preparing the
vehicle when the water touches the chain. I've tested mine on the Saladin and can confirm it works.
Photo of the bracket and chain. The chain is suspended from a pin that's mounted in a rubber bush to insulate it from the hull.
Andy
Andy that's an interesting application for the mod. But surely your water detecting chain is just the earthing chain that should be trailing on the ground before some of it snapped off?
