Not really, HF is not my thing. Currently playing with scatter on 24GHz.

NP 67 AA is the ERM for Truck Platform 4Tonne 4x4 (DSL) EURO 1 LEYLAND DAF NSN 2320-99-893-8860 Code DB 2091-3103 Here is a picture of NP 66 AA I assume your box is a BALUN transformer. It it used at the centre of a HF wire dipole (ie balanced) to match to a coax cable feed (unbalanced) to the radio equipment. Torroids are rather delicate and embedding in silicone gives some support. I expect there is a large torroid inside with appropriate turns wound through it. There looks to be an emergency spark gap should part of the dipole attachment fail then RF power could be dissipated to earth rather than cause a serious overload to the transmitter.

Paul no EMER, you need AESP 2320-D-128-811 Mods 11 & 20 https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/405637/FOI2015_01547_Percival_Landrover_Defender_Wolf_110_Annex_A_AESP_2320_D_128_811_2_45-O.pdf

I don't whether many members on here also visit ARRSE but on there can be found a wide range of topics which often degenerate into posters attacking each other, but through all this there are serious threads that can throw up interesting less well known bits of history. The Op Banner thread is one of the more serious threads, where I have been moved to make a post. I'll post my bit here if I may as it illustrates I hope that MV enthusiasts have something to contribute & a reminder that amongst all the silly questions we get asked about our vehicles & sometimes with no great feedback, there are some veterans out there with good memories & do know the difference between a Humber Pig & a Saracen! In the thread in question, a chance reference was made to cufflinks. So I posted this picture of a pair that I have that were made in NI in the early 1970s. (Those with good memories may recall I used these on a Mystery Objects Quiz, but the explanation I gave at the time was rather brief) This is the story of the cufflinks, which is a bit long winded I’m afraid. I used to have a couple of Humber Pigs which I would take vehicle shows that would receive varying levels of interest from visitors with varying levels of understanding. It was always difficult to know what level of information I should offer whilst the vehicle was being viewed. I found it hard to engage with visitors who declared “You can’t tell me anything about these, I know all about these mate, the good old Sarican” yet other visitors had more reasoned interest. I had two visitors who seemed receptive, so I mentioned that at one stage in N.Ireland up to 80 Pigs were in the workshops with wheel station problems. I explained a bit more that all Humber 1-Tons had Tracta joints but armoured Humbers (Pig & Hornet) had stronger rear joints, known as Chobham joints. These Chobham joints had articulated pads that were held in place with clips, which had a propensity to snap off. It was such a problem that rear Tracta joints from unarmoured Humbers were fitted and even new ones manufactured although that was delayed by the gas workers strike in February 1973. Rear wheel station failures were running at about 150 per month. So desperate was the situation was that the now notorious Chobham joints had to be scavenged from scrap Pigs, with knowledge that within 2-3 months they would fail. It is commonly believed than the stronger Birfield joints were fitted in Op Bracelet, as the Pigs were converted to so called Mk2 status, this is not the case. Bracelet 1 ran from September 1972 to June 1973, but by then wheel station failure was running at 120 per week. Of the 487 Mk 2 Pigs only 383 were subsequently fitted with Birfield joints, but this did not start until March 1974. This continued until October 1974 when the supply of Birfield kits ceased due to a lack of steel from West Germany for the drive shafts. My visitors seemed to take this all in without question, other than when they left, asking me “Will you be here tomorrow, I’m rather amazed that civilian would know so much about Humber wheel stations”. The next day they appeared, it turned out that one of them had served in NI workshops during Pig wheel station crisis. He revealed they were so exhausted & peed off by the whole situation that in the evenings a few of them occupied their evenings with the machinery in the back of a Bedford by making six pairs silver-plated cufflinks. He presented his pair of cufflinks to me, thanked me & walked off. The next year I didn’t see him but I recognised his companion who informed me that his friend had a major stroke & now knows little about the world around him. What happened to the other five pairs is anyone’s guess, they are not something that would be recognised for their significance. I don’t know what to do with my cufflinks, they deserve to be in a museum as it tells a back story to challenges of keeping a fleet of Pigs in operational use under very difficult circumstances. But I don’t trust museums to keep, let alone display such artefacts, which I think tell a far more interesting story than perhaps a display case with a uniform & some medals. In case anyone wonders on the factual content of above I went through all the REME SITREPS held at Arborfield & I believe I have every EMER that relates to Pigs.

Agree with Nick, I went for the first time last year & was very impressed by the exhibits & the helpfulness of the organisers. But my advice would be to avoid tangling with the M25, it took me 8 hours to get there.

YWE ?

Obviously you have clean fresh fuel. Based on my experience of similar with B60 I would check that the fuel filter is not full of crud, check that the bleed valve on the fuel filter is doing a proper job & not allowing air in. Test or replace the distributor condenser, with a new one, do not buy a NOS one as by now they will be very old & the insulation will have deteriorated. Check that the CB points haven't closed too much. Check the sparking plugs to see the state of deposits around the gap. File & clean & adjust as needed, but do not attempt this on the RSN13P plugs as you could break off or weaken the platinum side contact.

Somewhere(!) on this site there is a thread with 7 MERLIN XLS documents. I did a brief search but it meant trailing through 30 odd pages of posts. You may have more success if you tailor your search more specifically. Bear in mind these are only the ERMs that are captured by MERLIN, there are great chunks of ERMs that are not listed where vehicles went out of services some while back. As for official proper ledgers Wally would have been the man to tell us but sadly he doesn't come on here any more. Alternatively I think the XLS also appear as the result of FOIs to the MOD under the auspices of "What do they know?" I think Abbeywood were only too keen to get all this in the public domain to relieve some of the workload of FOIs that they receive.

Not sure if you are after the allocations for batches of vehicles or after the details of specific vehicles within a batch. A lot of work was done by the Road Transport Fleet Data Society in 1970s-90s who produced booklets on most of the series. These were based I think on records held at Beverley, supplemented by observations of vehicles seen. The EK series was covered https://www.worldcat.org/title/223703067 not sure if that is downloadable though. For more recent allocations there were a series of MERLIN spreadsheets released as the result of FOI requests to the MOD. I think there were a series of seven that had downloadable links that were on this very forum several years (5?) ago.

With you on that, which is why I have 8 editions & all of them different! Apart from changes to the main sections, there were a series of Appendices from A to K. Some of these were amended & sometimes displaced by an entirely different topic. To add to the confusion in 1951 all Appendices were re-designated as Annexes. Then new titles for Appendices were added to chapters of the main text with some of these Appendices acquiring their own Annexes.

Nice result Bob I'm all for 'bloke in a shed' workshop ingenuity making the most of what they have available.

Not this year it doesn't. https://www.gdsf.co.uk/

From RE Smith's classic book of 1968 British Army Vehicles and Equipment.

You can just make out the FVRDE Wing No 5968

I think that is the T.V. 1000 from 1959 at the time thought to be the most powerful wheeled vehicle in existence.

Well good luck with getting that back home. I will be interested to hear how you get on & any pictures are of interest as I might have come across it before. I might be able to help a bit with the history, sadly when vehicles change hands often important bits of history never seem to make it to the new owner.

If you look underneath you will see a drive shaft passing down from the gear box to the transfer box in front of the rear differential. There is then another shaft that travels forward from the TF box to the front diff. Check that only 2WD is engaged so that the elbowed lever to the left of the gear stick has its main arm horizontal & not leaning down which is 4WD. What Mk of Pig is it?

I live with a horse expert who cringes at historical films when she sees saddles, bridles & tack that were not around at the time. But it all looks ok to me. But show me any of the many films with Shorlands & Pigs painted grey or vehicles that were not around at the time depicted, I burst a blood vessel. Because with a bit more thought the correct advice & vehicles could have been sourced. Some of the advisors seem to have a poor understanding of what they should be advising. As I have little knowledge of WW2 vehicles & given the scarcity of such vehicles nowadays, the range of vehicles in this SAS series they seem to have made a good effort & seems to me to fit in generally. I don't know what a Reo is anyway : )

The number of aerials is inversely proportional to the amount of working radio equipment. If there is a flag then the chance of there being working radio equipment connected is minimal.

Yes I think you are on the right track. If Brown is the permanent unswitched supply but is not getting into the switch contacts then by picking up from Brown/White (the ignition switched supply that feeds the fuse bank) should I would have thought give you lights albeit only with the ignition on. Well done on getting the switch back together again with all those little springs & triangular contacts!

You have to bear in mind that when Chieftain went out of service in the 1980s you were not allowed to buy ex-MOD armour if the end user was the MOD. The first 6 Ferrets in private ownership here were imported from the Hong Kong Police by Mike Hoffman. At the time I couldn't buy even a Shorland, but was lucky enough to find one that had ended up with an end user other than the MOD. It is easy to forget how lucky we are these days with such restrictions lifted.

Mark I have EMER WHEELED VEHICLES F 238 Inspection Standards I can photo it BUT it is in fiche which doesn't do well when photoed on a fiche viewer as the centre screen being nearest the bulb gets well illuminated but the peripheral text is poor. I see you are after AC 12798 Pt 6 Supp 5 this is on the 19 Set Group site under reference no 677. But there are a few hoops to go through to get it & they may be uneasy about allowing access for general publication as I think they have to abide by some rules set by the RS Museum to control access particulary if it is watermarked by someone else.
