No doubt this would all be wartime stock. Hansard 10 April 1956 records the Secretary of State for War pressed for answer about jerrican stocks "Fifteen million, worth about £12½ million. Some are in use, some are reserves and some are being reconditioned or disposed of as scrap......... No new jerricans have been ordered since I have been at the War Office. The majority of this stock has been held over since the war."

Vision block, keep plate assembly FV811056 - modified

Nic I have a diagram of the modified plate but there are no measurements other than the relatively minor adaptations. It refers to the IPC 12559 Amdt No.4 Plate H13, Item 32. I have that it doesn't include Amdt No.4 although it has some before & after. It suggest the whole thing was a pain in that the IPC had to list a new item & a blue EMER was issued indicating that it had "immediate priority" to be carried out.

Never seen brown polythene ones Lizzie. It is often stated that green or black plastic ones were first made in 1966, well I have one of each dated 1965. I have never seen any earlier ones & that is not through lack of looking! Someone has shown me a green plastic one dated 1964, but it was a light puce green & of a different design. With the NCB of 66 rather than 99 indicated it was Australian. So perhaps the brown plastic ones you have seen were not UK versions given that the design as you say was to a different pattern?

Do you have the "Vision block, keep plate assembly FV811056"? There was a mod issued in March 1976 to modify it to prevent the swing bolt slipping out of engagement & releasing the keep plate. EMER WHEELED VEHICLES V 617 Mod Instr No.100

Yes well done Andy it is indeed that, in fact an ex-GDR RR66.

Yes well interpreted Mikle it is the latter.

PS Ah you're too clever for me Richard I think you might have picked up on "dwell" in my answer as a clue. Sorry it wasn't.

Good thought Richard but nope. If you are going down the speed line of thought you have to think very very very fast. This is not automotive as such although they were fitted to some vehicles or could be carried around. My German one I found got broken (this is it) & I have just bought a more modern Polish one albeit nearly 50 years old. The thing you see is just part of the equipment it goes to another unit (box of tricks) for processing.

Nope is the straightforward answer. (Well you did say "in any way" so not in the accepted sense. But once the answer is uncovered someone might argue that it does detect movement of a sort. But I would not dwell on this part of my answer too much as it may not help or on the other hand I suppose it might)

I'm interested in the four jerrycans. Three are black & clearly for water, but what about the other one is that stone or a light brown? If it was stone or olive drab then it would be for fuel, it seems a bit odd that it is stored mixed in with water jerrycans? If it was for water then it should not be painted stone as this could have unfortunate consequences for either people or engines as it could be confusing. In the immediate post-war period jerrycans for water were to be painted brown & then later black. Brown jerrycan denyers will sometimes quote a section of the Materiel Regulations that cover jerrycans suggesting they should be olive drab or stone, but this is in the section on painting POL equipment not water. The jerrycan of worms is here for those who want apoplexy this early in the morning: http://hmvf.co.uk/forumvb/showthread.php?25311-Metal-Jerry-Can-for-water So Lizzie are there any side on views or indeed any photos you have illustrating brown jerrycans for water as this is in the changeover period?

Nope not that sort of thing Tony

The outer casing that this has been withdrawn from is metal.

Nope not a geophone sort of thing Tony

Nope doesn't get hot.

Nope something more sophisticated.

To protect the object when it fits inside its cover. Doesn't get hot.

Its not that Richard, but a good bit of linking to past objects. But it is electrical but not low voltage & although it is German it is not WW2.

Good idea Chris but its not naval, this is German & land based if that helps.

Not unfair at all Chris as it seems to have been labelled incorrectly, if it had been that your conclusion would have been a reasonable one so its not that I'm afraid.

Good line of thought Rob, although the strips are for protection rather than insulation, not a heating element etc. If it helps this is not British.

Yes Richard well observed.

I see what you mean Andy but its not a battery.

Any ideas?
