Nope, on that basis my Shorland was made in 1909. 85 is a unique serial number preceded by the model parameters.

I have a couple of similar aircraft engineering books although not those particular titles which I imagine are fairly thick. Equivalent mechanical transport publications from the Army are not highly valued, but I find them invaluable for finding no nonsense straightforward old fashioned information. They are particularly useful in explaining things that sometimes one is too embarrassed to ask as you are expected to know that already. Although I am sure there must be many aircraft enthusiasts, I am not sure how many feel they need too much detail on the principles of aircraft engines. If the training books covered a particular aircraft or about flight instruments, radios etc they would be much more valuable. So I would guess you might expect to get something like £20-£40 depending where you try to sell it. I don't expect a military/aviation bookseller would feel they would be titles that would fly off the shelves & unlikely to show any interest. Apart from the unsexy content they will be quite heavy so postage costs will make them less saleable. You may be lucky & come across a collector of Air Publications who would like to add those volumes to complete a series on training books they are collecting.

Just had a look I seem to be missing a page. I have some details of AC1-AC42 and AC86-AC103. AC86 doesn't bear much similarity to yours I'm afraid: Engine no. 25306505J Chassis no. 25422843D Customer - G. Woodroffe who bought AC86-AC102 On the Shorland site there are a few manuals that may be of interest.

I'll dig out what I have later, but to be going on with AC3-LH-P-085 is the Shorts number. AC3 - Armoured Patrol Car Mk 3 LH - Left Hand Drive P - Petrol 085 - Serial Number

It is a Shorland. There are some pics of one used by the GNR in Portugal: https://www.shorlandsite.com/Shorland3apcGNR_Lemos.htm I have some lists of Shorland chassis numbers & Shorts serial numbers

Mike don't give up it may simply have been sold at another storage facility. I remember for years there were unexplained large batches of Champs that disappeared simply because they could not be found in Ruddington catalogues. I found that they were just sold elsewhere. Although Ruddington was a major disposal site, there were other disposal sites throughout the country. I have catalogues for many of these other sites, but need some sort of date.

If there was a Broad Arrow/Pheon/Crow's Foot signifying Government property that was on an item that was desirable to steal it would in close proximity to the WD mark. But a crown on timber or metal can equally signify this ownership: "The name of Her Majesty, her predecessors, her heirs or successors, or any public department, or any branch thereof, or the broad arrow, or a crown, or Her Majesty's arms, whether such broad arrow, crown, or arms be alone or be in combination with any such name as aforesaid, or with any letters denoting any such name."

It is tempting to think that but I believe that is a Scottish Crown. This would fit with George VI & SCWS. PS Sorry I misread that, when I jumped in I thought you were referring to the first crown which looked a bit Queen like.

I seem to have used up my uploads for that post. Here is the next one, but there are loads more charts, illustrating that Bridge Class is a very complicated subject & is a lot more than just the weight of the vehicle basis.

Mike this is from some notes I have made on the subject. Bridge Load Classification (STANAG 2021) Introduced 1960-63 The bridge load classification was said to originally have represented by the rounded-up weight of the vehicle in tons. "The new system relates to the characteristics of the vehicle which includes overall weight, number of axles, distance between axles, axle load (unladen & laden), tyre size, ground clearance etc and bears no direct relationship to the former system." It must be remembered that is a STANAG, which is a NATO Standard applicable to many countries. The UK had already taken some account of factors other than weight. What changed in the U.K. was that the mechanism for calculating a figure was now standardised with other NATO countries. The classification of bridges was also changed to take account of the effects that particular vehicles would have on the bridge. However, the application of the system is the same as before, in that only a vehicle load class less or equal to the bridge load class number may cross the bridge. The load class number is based on vehicles travelling at normal convoy speeds at a spacing of 100 feet. The classification also relates to ferries and takes into account an assessment of the state of the approaches to the crossing to produce an overall classification. There was no point in UK based vehicles having a Bridge Class displayed, as the Joint Service Road Transport Regulations JSP 341 states that: The UK will not prepare classification signs for civilian bridges and ferries in UK territory in peacetime. 1st September 1959. Originally issued as SDM(L) 219/1, Computation of Bridge, Raft, and Vehicle Classification. 26th February 1968. Reissued at intervals until SDM(L) 219/3 cancelled and replaced by Defence Standard STANAG 2010 revised and reissued as edition No. 3. Def Stan 23-2 Computation and Marking of Bridge and Raft Load Classification Numbers for Military Vehicles

Sorry Mike I don't understand what you mean. Looking for a sales catalogue without a date in mind is a needle in the haystack task. I have seen a Ruddington catalogue sell on-line for £100 so you need to be specific in the date you want. I have a number of these catalogues & could flick through a few to find your bike. But if you don't know when it was struck off or sold (dates are not the same) it is an overwhelming task.

Paragraph 2 is interesting. It might help dispel the belief that Bridge Classification is merely the weight of the vehicle & load.

Dave I would have expected some sort of list like that to be somewhere in EMER POWER O that covers Vehicle Electrical Systems (Commercial Pattern) I only have the bits of Section O that cover charging systems. No doubt they would be listed in terms of their component parts (but not function & properties) in the Vocabulary of Army Ordnance Stores Section LV6/MT8 but again I have not collected the magneto sections. Looking to the RAF in AP 1086 Section 16E MT Electrical Systems there are a handful of Simms magnetos again just parts but not properties, it does at least list applications (that VAOS doesn't) So don't know if this helps at all.

Indeed!

The coach looks like Mrs Thatcher's Battle-Bus https://www.theguardian.com/politics/2013/feb/22/margaret-thatcher-bus-under-hammer

Not to hijack Wally's thread, but Fox trials reminded me had this record of a rather pointless event.

The coil may have been changed from 6v to 12v if the ballast resistor has been removed. The original clamp with its warning may have been loosened & a 12v coil slid in. A Lucas coil should have the part number & date code stamped on the base (flat bit), this will indicate if it is 6v or 12v coil. Maybe the ballast resistor failed & a 12v coil fitted as a temporary fix or maybe someone thought they knew better than the designers & having a 6v coil + ballast resistor was a silly complication? Wired with a 12v coil it will still run but the performance will not be so good at high revs because the extra inductance of a 12v coil over a 6v coil slows down the rate at which the coil can magnetise & demagnetise. In other words loading the primary with more resistance & less inductance reduces the time constant of the circuit.

Wherever the resistor is located it might be as well to do some preliminary checks as it may be quite ok.. The coil is a 16C6 & would have a resistance of about 1.5 ohms, the ballast resistor would have a similar resistance. With the ignition on but not started, you should get 12v on the +ve terminal of the coil. When you close the points this should drop to 6v. This would confirm that the ballast resistor is working. It looks as if the ballast resistor is short circuited on running the starter motor. Incidentally the ambulance UHB says that the basic electrical system is the same as fitted to the 12v GS.

It's from the Ferret ISPL

Please post some pictures of around the coil & of the inside of the filter box. It is very difficult to visualise your set up. From the title of the thread & at the outset you asked for the location of the ballast resistor, by that I assumed you had a 24v system. But perhaps this is not the case & it is 12v, in that case I wouldn't expect there to be a ballast resistor. Do you think all the wiring is original or maybe a previous owner has made modifications?

John wow melted solder that was getting hot! Picking up on your point about a newly manufactured good quality condenser, I agree but it doesn't matter whether the condenser was intended for a 6v, 12v or 24v system. I just use condensers for a car (ie 12v) in 24v systems. It doesn't matter what the voltage is of the LT energising the coil, it is the Back EMF that comes from collapse of the magnetic field when the LT is turned off (ie points open) that counts. This is typically 300v so condensers for distributors will usually be rated for 500v although they rarely state that! If you see any sparks as the CB opens that is the 300v, it is not the LT supply. I've met a lot of people over the years who have wasted good money on "24v condensers" when a normal car one will do provided you find one of a similar size & clamp configuration. Because of the high ratio of secondary coil turns to primary turns, the Back EMF on the secondary is much higher than on the primary. Provided the coil is one designed for the earth system of your vehicle then this 300v will be of the correct polarity & be added to your HT. If you have vehicle where the earth polarity was changed & someone has just swapped over the coil LT connections then this 300v will be of the wrong polarity & detract from the overall HT output. Using a coil of the wrong polarity for your earth system means your HT system is 600v worse off than using the correct polarity coil.
