Nige don't know the date but probably fairly recent as it is in fancy colours & it was with a pile of stuff that included some Wolf documentation

Neil, go into the members section, the second sticky topic go into that about Sankey trailers the last entry is from Mike Allmey who has posted a link to his site with quite a few documents, but it doesn't have this one (sorry about torn corner)

Yes well don't rub it in. I have things going on here, I'll pm you on. But I dived in without thinking, I was tempted to modify the original post & extricate myself. But a bit of public humiliation I suppose is always entertaining! There is trick for testing the polarity of the spark to try to see in which direction the electrons are flowing. By holding the HT lead several mm from the plug terminal & interposing a pencil lead between the two a flare is produced. If the polarity of the HT is correct a flare is seen between the pencil & plug, reversed polarity & the flare is between the pencil & the cable. I have just checked that I have got it the right was round. But this book says that -ve earth or +ve earth coils may be used for either polarity of vehicle. But to ensure the polarity of the spark is correct then use the -ve terminal should go to the contact breaker for -ve earth vehicles & the +ve terminal should go to the contact breaker for +ve earth vehicles. So I wasn't 100% bollox after all ;-)

Ah yes I was forgetting that the polarity of the spark would be reversed. The problem is that the centre electrode of the plug should be -ve so that the spark jumps to the earth, wrong way round & a higher voltage is needed to get an equivalent spark. Also as the spark jumps it erodes the electrode a little & the centre electrode is designed for this. So I was talking bollox, so proper polarity coil for the appropriate earth system of the vehicle.

AFAIK the coil has no specific polarity & it was much more sensible when the switched battery input was marked SW & the other end of the winding that went to the contact breaker marked CB. Unfortrunately in modern systems it seems to be a -ve earth system then SW is now marked + & CB is now marked - I see no reason why the coil should not work in a +ve earth vehicle provided you translate it in your mind to SW & CB terminals. It would be important to be certain whether the coil is for a -ve earth vehicle or a +ve earth vehicle. I suspect but not completely sure that +ve earth vehicles used SW & CB whereas -ve earth ones use + & - It helps to remember the ignition coil is a transformer. The input (ie primary) winding is fed with switched battery supply (SW) & the other end goes to the CB terminal which is also connected to one end of the output (secondary) winding. The other end of the secondary is the HT output.

Roland, don't be misled by the 3-colour camo on the Mk2, it is nonsense & so are some other features. Mk2 pig was only deployed in N.Ireland, there was no requirement to display a bridge plate let alone a number on it. It is true that a few Mk2 pigs did have a plate left on from their former Mk1 life. But they were not picked out by painting it any diffrerently from the rest of the vehicle, nor was a bridge classification marked. For this reason the Mk2 was never given a Bridge Classification, which is far more more complex than just its weight. But given the classification for a Mk1 is '6' I think the guess of '7' is rather low for such a heavy vehicle. As for the Union Flag, pigs were not marked this way in N'Ireland. It served no purpose, the population was only too aware that these vehicles belonged to the British Army! I have seen about 6 Mk2 pigs fitted with turrets from Shorland armoured car (they are similar turrets to a Ferret). This served the purpose of improved protection for an observer in rural settings & the removal turrets from Shorlands was tried as a way of downgrading the "tank" like appearance, which always looks bad in the media. The turreted pigs I have were paint in just NATO IRR Green & that's all. The mesh is to give a measure of protection against the RPG7 & was fitted to Saracens in Operation Kremlin II from May 1973 & later a few Pigs. Interestingly when 12 BK 96 was a Mk1 it was sold of at Ruddington for £70 in 1968. But it was recovered in 1978 & made into a Mk2. This is much later than the main group of 200 which where recovered in 1972. I suspect it received the body of an already converted mk2 that had suffered damage to the chassis.

Just depends if you have been found out ;-)

Neil, well at least you had a go. It's not the winning that counts, it's the joining in.

The tone of the UH is that 35A rating applies to all four. Although one of them will not effect the running of the vehicle as it is just an auxillary feed to the NATO socket. The others are wiper motor, brake waring light & switches and the other is sidelights & brake lights.

Neil the UH just refers to them as 35A cartridge type Lucas 6FJ, so presumably all of them. I had a Dutch LtWt & that had 22 fuses!

Those Young Farmers are cleverer than you would think :whistle:

Luckily I got a pitch under cover but it was in the barn out of view to a lot of people. Took £23.50 on things that on the last three digouts nobody would look at let alone buy. Yet I had more of some previous best selling lines but no interest. Strange :dunno:

So I know its 24v FFR but what model is it? So I can dig out diagrams.

So what year is this trailer? My CAETE is 1994.

Someone on Ferret Heaven weighed his 2/4 turret (inc gun mount) & recorded 585 pounds which I think is 265 Kg. He may have been in the US, but are their pounds the same as Imperial ones? Is this on your Shorland? It may be slightly lighter as contrary to popular belief they are not Ferret turrets, they were manufactured by Shorts themselves admittedly based on a Ferret turret.

The range of stuff would be covered in CAETE (Compendium of Army Electronic Test Equipment) got one somewhere. Of course the CES would define it, I'll see what I've got, give me a few days.

I think I have some of that sort of paperwork, but give me a few days.

Neil I am always suspicious of the earth on these side & esp rear lights where it can corrode with mud & disimilar metals. I would (via fuse) take a direct lead from 24V + to the feed lead of the indicator bulb, if it lights up at least you know the earth, the bulb & it connections are OK. Then you have to figure the flasher connections when I get a chance I'll look up in the book etc, but got things going on to take my time at present.

I have seen individual vehicles fill up. An Army carawagon once & of course didn't have a camera, & odd RN vehicles. But I have never seen a RN convoy so they have to fend for themselves on an individual basis I suppose. Once I was filling up in my carawagon & I had a squaddie turn himself in after AWOL the day before. He tried to insist I took him back to camp, had great difficulty getting him understand my vehicle had civilian number plates!

Lee, I have the User Handbooks for MOBAT, WOMBAT & CONBAT. Below are some pages on the No.73 Sight. I only have the IPC for CONBAT but that uses the No.75 Sight. However looking through the parts list in addition to the NSN most are given a drawing no. either prefixed RCL or BS & a few FV. Where a manufacturer's no is given the manufacturer is stated, so this does indeed look like a design drawing number. Curiously in the column includes ADFRENO, which as we all know is a RN stores cataloguing system. So did they have BAT guns on board ship?

But if you are in The Netherlands, the lead vehicle has two blue flags (one each side of cab) the rest of the convoy each has a blue flag except the last one which carries a green flag. I wonder why it is different over there?

Well Gareth, what about the Christmas colour scheme shown in your avatar? It would at leat be authentic if not a bit unseasonal.

Perhaps a clue here, Penal Servitude i.e imprisonment with hard labour was introduced in the Penal Servitude Act of 1853 and was abolished in Criminal Justice Act 1948

I don't think primer & then a coat of IRR NATO Green will offer very good long term protection. I try to follow the 1948 spec for AFVs which is primer, the Dark Admiralty Grey undercoat & two layers of high gloss Deep Bronze Green, then NATO IRR Green if desired. I assume you mean NATO IRR Green this is nothing like the protection of proper gloss paints, however there is a NATO Green high gloss used for non-tactical vehicles but it has no IRR properties. As for heat resistance British Army postwar engines in general have used Sky Blue heat resisting gloss. But I had a pig from N.Ireland service that had the whole engine etc painted in IRR NATO Green & showed no sign of failing due to heat. BTW Looks cute, at first looked as if it was a baby Stalwart!
