That looks like the Tent, Marquee, Universal, Hospital, Extending 8340-99-942-4586 that is the postwar version. If you are a WW2 group do you have the earlier version JA 2080 with very few "windows"? I wonder do you have the extensions? Well it should talk 12 men an hour to put up. I have the wartime instructions I can scan in due course.

Yes Wally it gives me a chuckle when I see that owners have restored their vehicle with the stencilling they have found under the paintwork & then put all the unit markings they found on it as well. It could either be presented as a vehicle marked as when stored in a depot with no kit or unit markings. Or with the unit markings & kit but with the depot markings painted out as they were required to be on issue to a unit. But its a touchy subject often people don't like to hear that. Yes I know people can paint whatever markings they like on their particular vehicle, but its not quite right to present it as genuine history because all the markings would not be there at the same time.

Grey was introduced by CRAOC orders late 1977 then soon changed to same colour as the surrounding green or black the plate was positioned on. I wonder if the bridge plate was where they put the temporary vehicle depot markings, which would include asset code, reliability classification, receipt date. When they leave a depot these marks should be obliterated.

Yes I see what you mean it looks like gloss black.

Simon I think that is because it coincides with a black part of the disruptive camo that should generally have black bits on corners.

Hard to tell Simon without a picture

Thank you Steve, that's in the diary now.

Ok thanks Ian

Introduced in 1982 carried into 1983, then when the commander of the armoured squadron left went to DBG. But when he left reverted to the urban scheme. To find that point you need to find when the new commander, who came in 1983, actually left.

As far as B Series engines & their ancillaries go, in the earliest handbooks & parts books very often the engine & fittings are all in black. With rebuilds & replacement bits it all seems to morph into Sky Blue.

Trying to plan next years holidays. Is there an Evesham show in 2014? Any dates confirmed please?

Trying to plan next years holidays. Been on the club site but only has the old 2013 info. Does anyone have the dates for 2014 show please?

Depends what the plugs are that you've got. Its good that your system is running very well so be wary of fiddling around until you've broken it! I have done a lot of tests recently on various screened plugs but not unscreened ones. I tended to assume most these days had some resistance built in. I would put on ohmmeter on a plug & measure the through resistance. 1k-4k is needed to reduce erosion but & 10k-20k to reduce RF interference. But in either case it doesn't matter if that resistance is in the plug, the leads or suppressors screwed into the leads. I've heard it said that you should open the spark gap now you have electronic ignition & have more voltage. I once did that & got to a show checked in then the Pig wouldn't start. Changed to normal gapped plugs & been ok for years since. The thing to remember that although you might observe a good spark in a plug it may not be so good when under compression in the engine when a higher voltage is needed especially if accelerating & under load. Nope So just measure the plug resistance & if its a few thousand ohms then I would relax & enjoy the satisfaction of it running well

Yes once you asked if it was navy I thought someone would then have said Army or RAF? Then I would have said under Air Ministry control. Then from the time frame I gave I thought the game would have been up. Although only one person fell for the sausages asking about fresh meat :-D:-D

Yes Wally spot on. These represent ROC fallout monitoring posts & in the mapping room the disc placed on the map board drew attention to the fact that for whatever reason they were non-functional. In fact one forum member has one of these OPs, I thought he was going to come on & get the answer!

Nope Wally but cold war! You are getting warm :-D

Lauren nope not that

Lauren nope but some good lateral thinking that is needed as there has been a lot of focus on artillery etc. These counter discs, as I said earlier, were in used mid 50s to mid 90s.

Wally not that sort of thing at all.

Not that Wally.

Nope Tony not artillery related.

Nope Richard the gap is solely so that the designation of the OP can be identified on the map. Umm just got up then?

I've let the cat out of the bag now I'm afraid :-D

Lauren no not that. I think I'm going to have to say the reasons as it so difficult to guess then I think people would stand a reasonable chance of working out the units that used these OPs and the purpose. Blue point - Nobody there Red point - Telephone fault (should have stuck one of those on my house for 2.5 weeks!)

I assume you are talking about an unscreened 12v system rather than a 24v screened system. You need to have some resistance in the HT circuit not just for RF suppression reasons but to limit the spark erosion taking place at the plugs and the distributor cap. Some people are prejudiced against suppressed leads as they don't like the idea of any resistance reducing the voltage to the plugs. But because of the low current the average lead might cause a voltage drop of 10 volts which is nothing from 10kV or so. The problem with these suppressed leads can be if the terminations get damaged or you try to change them. But if you use copper leads it would be foolish not to use resistive plugs. Even if you have suppressed leads if you have suppressed plugs as well you will lose very little HT especially as it has more output now that you have electronic ignition. You will also have enhanced RF suppression as the resistance to be of benefit for suppression is much greater than for the spark erosion reduction.
