Largely my work with different photos.
Compare and contrast the photos to those in this thread... :mad:

Thanks to Dave C for this film find of L5295052: http://www.britishpathe.com/video/stills/fire-in-german-farm-house

Nice find - I'll post it on the Army Fire Service pages as well.

...the whole rear bogie is designed to be as flexible as possible and is quite a complicated setup, not sure i understand quite how it all works yet.
As I understand things, the intention is that the springs are only subjected to load carrying forces. Torque reaction is not taken from axle to axle but from each axle to the chassis frame by the short rods between the worm casings of each axle and the cross-member midway between them. Thus the torque produces no vertical load components. When torque reactions are not balanced like this, the leading driving axle tends to lift and the trailing driving wheels to dig in the ground.
The worm shafts also remain parallel and thus the angular velocity of them and their wheels remains unaffected.
With regard to the laced spring, I wonder if it is to ease the twisting that ocurrs when travelling over rough ground - if say, on one side, the leading wheel were raised and the trailing lowered, the wheels would be leaning in opposite directions from the vertical position, causing the springs to twist?

The collection was featured in Wheels & Tracks - from memory it is located in the outskits of Vienna (Wien). I'm not aware that it is open to the public.
For others, the link is here: http://www.militarymuseum.at/Website/Welcome.html

The "C" type range of models included:-
C11/30 = 30 cwt, 11' 2" wheel base, four cylinder engine, normal control
CS11/30 = 30 cwt, 11' 2" wheel base, six cylinder engine, normal control
CS11/30F = 30 cwt, 11' 2" wheel base, six cylinder engine, forward control

I note he is still selling some MW related bits.
Such as this item, said to be MWR:
-
The government public consultation period closed back in January and the decision has been made so not sure what a petition will do now.
The public consultation may be over but the legislation isn't in. The Goverment can always make a U-turn when drafting the legislation; and, if being made through primary legislation, the Opposition can table amendments, or, if secondary, can call for a debate.

Looks more like a half-Nelson LeMoon.

Sadly not, but some of the pictures in Pat Kennett's book on Dennis may help.

This is a 6-cylinder De Dion of circa 1910.

Kelly Springfield, me thinks.

I was under the impression that the 30 cwt wheels I have for the Vulcan were 24" rims, as they are supposed to have 33 x 4.5 tyres on them. However there doesn't seem to be any part of the wheel that measures 24", is it one of those odd tyre sizing things that i'm unaware of, or are they just not 24"?
An article on the VSW in Motor Transport, February 21st, 1927, ends:
The single tyre equipment consists of 33 x 5in. pneumatics on all wheels, and the twin of 32 x 4 1/2in. on all wheels - twin tyres on the driving wheels.
Applying the formula mentioned above this would mean 23in. wheels. Does that help? Of course, that's not to say you actually have 23in. wheels...

If this workshop is supporting medical services, I see no problem with it bearing a red cross symbol.

An attractive alternative to olive drab - a home front Napier, taken from The Motor World October 7, 1915:
The Government recently gave their permission to the various motor car manufacturers to deliver a limited number of vehicles to firms and traders in the country engaged on Government work. This was undoubtedly a timely move on the part of the authorities, as many firms who are straining every effort to supply war material have been handicapped by the lack of adequate motor transport. On this page we illustrate one of the first vehicles to be delivered by Messrs. D. Napier and Son Ltd. This was supplied to Lang Propeller Co. Ltd., Weybridge, who have large contracts for propeller blades used in connection with the air service. The chassis is the well-known 30-45 cwt. Napier model, which has been supplied in large numbers to the British and Allied Governments.

An enjoyable film this, with a thread running here: http://hmvf.co.uk/forumvb/showthread.php?31739

Another clip of one here at about 3:50 http://www.britishpathe.com/video/desert-workshop
Several other Scammell Pioneer clips out there :cool2:

Cheers, Tony. No pressure then. I can't name the type precisely but it looks like an early 1930s model. There'll be someone in Thornycroft Register who can provide chapter and verse: http://www.thornycroft.org.uk/index.htm

Frederic, don't be pt off - French vehicles are something few us know much about. Please educate us.

I have been looking at the Warland system as used on silver ghosts, this system appears to be the same as the period photos.
Tom, you may be interested in this letter from The Motor World, January 24, 1918, confirming the use of Warlands on these trailers:
Sir, An article in a recent issue of The Motor World suggets that wood wheels on motor vehicles operating in war areas have failed.
We have no exclusive interest in wood wheels (although our wood-wheel plant has been described as the most extensive and best organised factory in this country) since, our special concern being the maufacture of a quick-detachable rim, equally applicable to wood, steel, or wire wheels, we are almost as much affected by the one as the other.
Obviously, therefore, although we are not a disinterested party, we are rather more disinterested than manufacturers associated exclusively with a particular brand of wheel. Our position may, in these circumstances, justify a reference in your columns to the alleged case against the wood wheel and the implied championship of a certain form of detachable wheel not made of wood.
What we desire to point out in this connection is that, although we have made thousands of wood wheels, and have equipped these and thousands of other wood wheels with Warland Dual rims; and although these range from light aeroplane trailer wheels to the heaviest twin pneumatic-tyred wheels for armoured cars and other weighty military vehicles, we have no record of a failure, either of our rim or of the wooden wheel to which it was fitted.
That, naturally, appeals to us, and, we suppose, will appeal to most other people, as fairly satisfactory evidence in favour of the efficiency of wood wheels under the strenuous conditions of war. It is certainly not evidence in support of the assertions of non-wood-wheel exponents...

It's surprisingly difficult to find Humber FWDs on archive film. I don't know of any other footage of an FWD PU 8cwt. These are the only, somewhat brief, clips of a FWD heavy utility that I've found:
@ 4:37 http://www.britishpathe.com/video/stills/victory-in-tunisia
@ 5:05 (just!) http://www.britishpathe.com/video/stills/invasion-scenes-europe-british-troops-7
@ 0:31 (again, just!) http://www.britishpathe.com/video/stills/stores-depot
But slightly easier to find footage of the FWD ambulance:
