I don't think they are stones, as you say 3 inches is rather narrow. The materiel was not specified, this is from an Administration in the Field publication, so it would only be a relatively temporary marker.

Yup. Anybody suggest what religions these three markers indicate?

Yes Robert well done! But what do these different shapes signify?

Nope

These are all very plausible & ingenious suggestions coming in, but nope.

Yup they are markers, but for what?

Nope

What are these for?

Well done DB I knew I could rely on you to have a go. You have scored 11 points & no errors. But you have missed a few. However I think I screwed things up a bit. :oops: I excluded draught animals, I shouldn't have done this. So I will modify the question. So you & Tony might want to have another bash. Although where either of you mentioned draught use, I have counted it as a point. I was going to rebuke you for the monkey & pin comment, but looks as if you might be right ;-)

I agree that with a poor earth, it adds resistance to the circuit & the voltage across the bulb changes ie goes down. By Ohms Law, as the resistance of the bulb is fixed, as the voltage across the bulb goes down, so must the current decrease, it cannot increase. But the voltage across the whole circuit (wire + bulb + poor earth) is fixed by the regulator & cannot change. I don't see how the bulb could draw more current? All 1-Ton Humbers have a 24 volt supply & of course all bulbs including turnlights are rated at & supplied by this 24 volts. However for improved reliability the turnlights on the Hornet are rated at 12 volts & supplied by a resistance fed from the flasher. Sometimes I forget this, if a turnlight bulb is damaged, I have made the mistake of fitting a 24 volt bulb. The bulb glows dimly, it doesn’t glow to full brightness because feels it should demand more current. In fact when I have left a 12 volt bulb in place for a while it would seem to be less prone to blow. This wrongly fitted 24 volt bulb doesn’t know why it has a reduced supply whether it is deliberate resistance or resistance through a poor earth. I agree that wires around a poor earth will get hot & can even melt. The heat from the poor earth like any resistance is proportional to the square of the current times the resistance. This heat is at the point of the poor earth but will be conducted thermally along the wire feeding it, getting cooler the further from the poor earth. The bulb that it is associated will be no hotter because of electrical activity from within the bulb. But as you say the practical points are to make sure you have a damn good earth & establish that you have the correct voltage from the regulator & see what happens to it after that. PS I wrote all this waffle an hour ago, went to preview, wouldn’t let me preview, try to go back then whoosh its all gawn. So did this in Word then pasted it, not getting caught out again! Computers ggrrrh :computerterror:

Under Ohms Law if you increase the resistance & the voltage, which in this case is fixed by the regulator, then the current must fall, not increase. For example take a circuit with a resistance of 3 ohms & a voltage of 24 volts applied then it will draw a current of 8 amps. If the resistance was increased to 4 ohms with the same voltage of 24 volts then the current falls to 6 amps. So if the current falls then less heat is generated, so less likely to blow the bulb. If what you say is correct Tony, if you ran a 24 volt bulb on 12 volts it would be more likley to blow. The bulb doesn't 'know' why it has a reduced voltage whether comes from a 12 volt battery or the effect of a 24 volt supply but subjected to resistance in its circuit from a poor earth.

As they used to say "Drop your doors and the money's yours!" Isn't it nice to know that dealing with a British vehicle like this that the rear door aperture is exactly 4 ft 0 in, nice'n logical. Engine? yes that would be nice, we need to sort something out.

Not sure I understand that. With extra resistance due to a poor earth, I agree that heat will be generated at the point of the poor earth, but the extra resistance will mean less current flows through the bulb, which wouldn't make it more prone to blow. The most likely cause I would have thought would have been a fault on the generator panel. I once found mine was not regulating properly & giving an output of 30 volts!

If its a No. 2 then its a 25 amp dynamo. It has gearing that comes into play so when the revs drop below 1200 rpm ish that the speed of rotation of the dynamo does not drop significantly. This means that it can still deliver its full output down to a few hundred rpm unlike a normal dynamo that is useless below 1000 rpm. (I am assuming when you said Mk 2 it was a typo for No. 2. The Mk is just the variation within the model, the No. is the crucial thing in defining what you have got)

Yes, the two braziers were provided for heating. The equipment was universal for all ranks, but no doubt there were special allocations for specific ranks to use. Neil was rather too precise about ORs, but I think he was 99.9% there.

Well done Tony for taking the plunge. You scored 7 points (won 8, lost 1)

Relax, you are not mad! It was the TV version of "The Navy Lark" http://www.bbc.co.uk/bbc7/comedy/progpages/navylark.shtml

Maybe next year, if your report on it is good. I'm sort of out of show mood now its colder & unpacked stuff thinking the season is over :cry: Also behind on an article I'm doing but slowed up with building work dragging on & not easily able to get to my books to refer to.

From time to time the British Army has used animals of varying type & size to transport goods. I have identified these from documents dated from 1884 to 1959. Who can identify these from the list below? These are pack & draught animals; I am not including mascots, animals for food or for message carrying or security etc It may be that other animals have been used but I have included only those identified from lists together with some that definitely were not! The scoring is for a correct answer, one point (un point). For an incorrect answer you lose one point (perdez un point) Ass Bullock Camel (single humped) Camel (double humped) Cat (felix domesticus) Dog, GS Dog, RE Donkey Elephant Emu Homunculus Jennet Kangaroo, GS Mule, GS Mule, Pack (Sudan) Mule, RA Pony Rhino Sheep Water buffalo Yak Zebra Updated Sorry I scr*wed up. It it now incudes draught (ie pulling) animals not just pack animals.

Yes well done Neil, you've got the answer. It is for drying clothes in camp circa 1921. The prize is to collect my dirty washing & show us all how the equipment is used 8-)
