Oh dear that will be the end of an era.

Thank you for doing that Richard. I think I'm sorted now. It has now been superseded by ver3.4 only changes are on pages 26/27 where there is some clarification about replacement diodes & further suggestions.

Chris that all sounds very feasible. Annoyed I didn't take a picture of the inside when I had the chance (the item is not mine) What do you reckon on push-switches A, B & I? I'm trying to envisage what electrical role they would play in the switching. Maybe being 3 switches they could rearrange the sequence of the 9 key switches, so that even with 9 switches selected at the press of a button each trio could be put in a different order, allowing instant changing to two further sequences of Morse characters? PS Or were you thinking, pressing say I made 'normal' keying, then say A pressed space & dash swapped. Then pressing B space & dot swapped for instance?

There have been a few changes to Def Stan 00-23 IRR Requirements for Painting Military Equipment Issue 1 17/10/80 Issue 2 31/12/98 Issue 3 30/5/01 Presumable a change in IRR pigment properties might also have some visual changes as well. BTW unless you are a registered user you can no longer access Def Stans on line. http://www.dstan.mod.uk/closure_notice.html

The original screen EMER was issued in Jan 76 & the retaining chains May 76. Off hand I can't give you a date on the solid ones. I think I may have a spare down pipe, but getting it to you will be a problem. I no longer have any visor hydraulics. Is it the pump or the ram that is leaking? I can give you the part numbers for seals as appropriate. Afraid scanning the CES will have to wait for now as I'm getting swamped with all sorts of requests coming in from all directions & have large backlog. I'm not very up on uniforms & accoutrements, best thing is looking at period photos & if there is vehicle it might be possible to date if from the fittings on the vehicle.

Pages 9-17 http://books.google.co.uk/books?id=v6zZuq7nSZQC&pg=PA11&lpg=PA11&dq=hitlers+gold+bridge&source=bl&ots=D0yTMvxWLb&sig=NhCiY4rDXWy2IQxr06AcfmMCtbA&hl=en&ei=QWqMTpXzEsbE0QWRv9HYBQ&sa=X&oi=book_result&ct=result&resnum=3&ved=0CDIQ6AEwAg#v=onepage&q&f=false

Yes Richard switching codes in a sense. It seems to be a programmable keyer for Morse code characters. I built one using a chip so that I could send my callsign automatically at the beginning & end of a transmission or in a repeat cycle to identify my signal as a beacon. When the motor inside this grey box rotates it switches in turn the selected dot, dash or space of each of the key switches in the manner that has been selected. I don't think this would be for lamp signalling. Too complicated a device for a small signal lamp & inappropriate for a large lamp where the keying is done with shutters & the lamp is on all the time because of the time lag in heating up a large filament bulb. So I'm sure it is a programmable Morse keyer. But no idea whether the signal it sends is an indicator of the code/cipher that the message will be encrypted in, a station identifier preceding/ending a transmission, a continuous beacon identifier (for navigation or IFF) or triggered by an IFF interrogation signal/command.

Some interesting reminiscences there Tony, but I can't follow why it would have anything to do with magnetrons which require tens of kVs.

I can supply a tube, mount & a record sheet to go inside. Although is not a particularly important thing to fuss with. That sheet contains details of all the EMER POWER Mods. 34 BW = Donnington Hose, front inner, (total length 13 in), LV6/MT1/AU/LK/KL49404, new no.KL107804L, 2530-99-800-4217 Hose, front outer, (total length 15 in), LV6/MT1/AU/LK/KL49406, new no.KL107806L, 2530-99-800-4218 Hose, rear, (total length 17 in), LV6/MT1/AU/LK/KL49808, KL97716L, 2530-99-800-4221, MOD1132 AFAIK the only person doing repro hoses is: http://www.champ-sparesukltd.com/index.html Be aware that the fittings will match but the bore is smaller. So you wouldn’t want a different type on each side as that would give an imbalance in braking. But won’t matter if you replace them all, which is a good idea anyway. You may find it cheaper to get some made up locally. I have identified the front ones match up to repro ones made for MGA cars, although these have smaller bores as well. Hose, front inner, (total length 13 in) = SBR053 Hose, front outer, (total length 15 in) = SBR051

Oh what a give away. Don't tell me you used to go round pressing button B to see if there was 4d left in there by a previous user who couldn't get connected:wow:

Chris I don't think it is RAF as there are no familiar Vocabulary codes. I think "Pattern" is more leaning to Admiralty Pattern & indeed the key switches all have Admiralty Pattern numbers on them inside. Unfortunately I omitted to take an internal view. Inside there is small electromagnetically driven selector switch with perhaps nine banks to match the key switches. It resembles a small version of telephone exchange selector. I'm sure you are right Chris that it is some sort of IFF system whereby a Morse code identifier can be programmed by the key switches. To what system it is linked to I do not know. I imagine the speed of the keying is fairly rapid. So I don't know whether the keying is initiated by receiving a triggering signal to interrogate it, whether it is a continuous (please do not attack me) beacon or whether it might be auto-initiated at the beginning & end of a transmission of messages. I wonder whether it was used to send an identifier or whether it was a way of specifying the code that a message might be encrypted with. A, B, & I are push button selectors. I note that it is to be used in conjunction with REC. P43A. That sounds like a receiver but I can find no references to it. I used to have an Admiralty Receiver I think it was a P58 that covered something like 400-650 Mc/s, but I can find nothing about that either. If all else fails on here & nobody recognises it I may contact http://www.rnmuseumradarandcommunications2006.org.uk/

Well done for having a go, but I know you do like these sort of challenges:D Naval yes, because the front of it has a "Pattern no" & inside the switches have "AP" numbers. Not an intercom but I can see your line of thought. There are some security aspects to it. I don't know the era but I would have thought 1940s-50s. Time to show a bit more.

I know what it is & which service used it. I think I know how it works. But I don't know the bigger picture of its particular application & what it worked in conjunction with. Anyone?

The User Handbook will only give you quantities of fluids not their type as these may be subject to change from time to time, that info is in the Servicing Schedule. For engine AND gearbox OMD110 = SAE30 For TF box, diffs & axles OEP220 = EP90 But I had a lot of trouble using genuine OEP220 in transfer box. It overheated would boil out through breather & force itself into the rear diff. This is a badly neglected area where many Humbers don't get the levels checked. I used Comma I think it was 85 EP oil & no overheating at all. The lubrication nipples on the Tracta housing are for oil to be injected. They are not intended as greasing nipples. Oil should be injected to the point that it flows out through the holes when you remove the oil level plugs, they are NOT oil filler plugs. When people do bother to do servicing it is very common to see evidence of grease injected into the lubricating nipples. The last published Servicing Schedule specifies OEP220 & indeed the procedure to follow is not new it was described in in User Handbook going back to the provisional User Handbook 1953. Plugs? Well this is an old chestnut & no doubt others will come on to tell you their take on the subject. I use RSN13P they keep clean as I am using electronic ignition. Never adjust the gap as the platinum point will ping off as you do it or worse when it is in the engine. You can use RSN12Y (as in FFR Rovers) & you can adjust the gap particularly if you have electronic ignition. However I did do this & at times had unreliability problems so I went back to RSN13P although no doubt others will say the opposite. Points? Get rid of them & fit a Joley electronic system. But I feel you should stick with the original coil. There is some coverage here: http://www.hmvf.co.uk/pdf/IGNITIONMATTERS.pdf

Seoirse, well there's no disputing that. Sorry I can't find a match. I wonder when then engine changed, has it got the engine modification sheet rolled up in the holder up by the thermostat?

Can't find a match for 9831. In the 4-digit engine numbers for Humbers the highest I can see is 9359. You're absolutely sure it is 9831?

Paul perhaps don't get too carried away, it's always a shame to see a nice vehicle that I can't really photograph because all its detail is submerged in camo nets, which after all is the purpose I know. But strikes me as a shame when people bring nice vehicles they have restored often a considerable distance to render them largely unseen. By all means camouflage the family, the bar & the living quarters but a shame if we can't see the vehicles in their detail:D

Major clubs have a Verification Officer, I needed a letter from them & can show evidence of the chassis plate on the NS in front of the front wheel (not the body plate in the cab). Although most vehicles I have had were still inspected. But I don't know how the system works in your part of the world.

I have a CES for a Mk 2 also an unofficial CES document I found in between the spaced armour on mine. Yes you are right deciding on a particular time is the crucial point to how you present it.

Seoirse welcome on here, now I hope you are not going to neglect that Shorland:D

This is what I have been hunting down for years. Beneath the recent gloss black there is BROWN PAINT. This is painted directly onto the metal. Beneath the black there are some traces of red on top of the brown.

I sold a set of 4 tyres on wheels some 18 months ago. I have a spare set here but I'm hanging onto those until my time comes I'm afraid. All I can suggest is you will need to look for a Mk 2 that is seriously mechanically compromised but with ok tyres. Swap the wheels, take/sell the bits that you need then weigh it in as they say. Terrible thing to say I know, but there aren't enough original tyres to go round. Very occasional odd ones do turn up when someone is having a clear out or moves etc Notice I say Mk 2 don't use Mk I tyres on a Mk 2 as they will not be strong enough & besides may be 15-20 years older. Mk 1 marked HS RF Mk 2 marked REINFORCED There is a chap Sussex way with a Mk 2 who fitted some sort of lorry tyres a few years back & he seemed to get on fine with them. But not being runflats has to carry a spare around.

Did these come from Sturminster way in Dorset?

My thoughts as well Andy. Once I had sorted some messages I was going to post something similar in case it looked as if we were ignoring you Jamie:D

In case people wonder what has changed yet again! The version (V4.3.1) posted on 8/9/11 was a major upgrade in alternator construction and testing, there are 18 additional pages with 30 new images. The version (V4.3.2) posted today 12/9/11 corrects about 20 dyslexic errors that defied my repeated checking until it was uploaded when they all became embarrassingly obvious. In the light of more data purchased a few days ago I have been able to expand the section the diodes types used in the generator. If you enjoy part numbers, CV codes, NSNs etc then this section is for you. As this is a living document, rather like an EMER, sections can be amended & added to make it as comprehensive as possible. I am particularly keen to hear from anyone who can add any data or references to the generator diodes of their various kinds.
