There was an AV760 for sale on this forum not long ago, In Aberdeen I think. (MK3ian)

I have never seen a one before. Thank you for posting a picture and information, It actualy looks stylish and as if it could do a job. I can see where the design had influence on the Martian.

We know what it should be, we can see what it looks like, the image is nearly right, the camera never lies, it just clouds the issue sometimes. But the jury is still out.

As the third diff was added basically as an after thought I would have expected it to be a pain.

In the brake line scematic of the Crane/Rogers 40/45 ton trailer two air filters are shown one on each line. I cannot find any maintainance instructions for these, but by now I would think they will need cleaning. Brake line filters and silencers have in the past given me a few problems and been the root cause of some trouble. Slow brake reaction and release being one symptom.

That is a giant truck is that the Leyland behemoth, dwarfing what looks like an early Champ. I would imagine loaded the centre of gravity is high. A design concept.

As far as I can remember the last 50 ton Dyson I saw was in the 1967 at Blyth Dry Docks and Shipbuilding when it closed down. I think they had two. A DT and trailer doing what they do best, even better if it was carrying a Churchill. As designed. Thanks for posting.

I think the Antar concept started as an oilfield hauler. An inter axle third diff was incorporated at their request. When used on the Snowey Mountain project they were having problems with lubricating diff bearings because of the slow speed high load operation. Austrailian engineers designed a local fix pumping oil to the affected bearings keeping engineers at the factory informed. This led to factory modification to cure the problem on later trucks. I think this was after a much larger Leyland prime mover was cancelled.

I thought there was a fire box in one of your posts, If a friends trailer is close that means photos of a brace of M19 transporters is possible to look forward to.

That rig has gone back home then. Dyson s FV 1301 50 ton drawbar trailer seems to have been in service well before the Antar came out for road test.

Your welding is art in its own right.

I think there was an M19 rig for sale on this forum early last year.

A 10 hp Hillman supplied during ww2 would not have that type of small lights on the front mudguards and no light on the rear quarter. They would originally have had semaphore signals I think and mechanical brakes. If you look on the firewall you should be able to see the blanks covering the holes for the steering colume and pedals for the right hand drive version.

Where is the photo interpritation unit of RAF Medmenham when you want it. A few dimentions- Diamond T Length 23 feet 4 inches Wheel Base 14 feet 11 1/4. Mack NO2 L 24f 5in. WB 15 feet. Albion CX22 L 25f 6 in. WB 14f 8in. Mack has a high front end look because of the front axle steering mechanism necessitating a high front axle. Mack still appear to use this type of steering drive transfer without C.V. joints to this day.

Ah ha, a vehicle type owner has broken cover. Also left a teaser about a forthcoming restoration thread.

Greyhound32122 is renovating a Diamond T ballast tractor. Sandstone project are renovating a DiamondT and Rogers trailer to go with there Sherman 1V. There is also a Rogers trailer being renovated after being retrieved from a scrapyard on Malta. When things return to some sembalance of normality I would think the ones at present in there lairs will put in an appearance in the U.K. I wonder if there was a good outcome for the trailer in a Quarry that the owner could not be found for? Another question did the military run any Federal prime mowers in the U.K. as they were supplied under lend lease and have more front overhang.

Just trying to come up with plausible alternatives. It may just be an optical illusion creating the difference. Going around the known suspects I now keep coming back to a 4 axle 32 wheel 50 ton Dyson loaded with a Sherman Dozer hauled by the usual suspect.

Looking at the pictures until my eyes hurt, I wonder if in the second picture the prime mover is passing something giving the appearance of a longer nose. In the first picture a D.T is the most obvious candidate. Possibly a 981 with the winch rollers in the front bumper. Oh for a better picture. Possibly the scale model makers could take a relative pic. Or a real one even better. Physical size and date, of even a prototype puts an Antar out I think. They could be different vehicles in a convoy.

This trailer appears to have 4 axles with a tappered profile to the bed, which would put it in the 50 ton Dyson range. I think the profile of the towing unit is wrong for a Diamond T, I think the front axle overhang is to long. I now duck behind the nearest solid structure.

Thank you for you dedication to collecting and reporting the facts, Your mastery of english is far better than any attempt I could make at your mother language.

I think Diamond Ts came originaly with a Rogers trailer, then later Crane and Dyson trailers as well.

I have been looking for some of the airlines and connectors some I have not seen for a while.

A term that little oft ignored voice playing in the back of your mind (buyer beware) comes with any second hand vehicle.

Quite a bit of detective work to do.

A good clean with a wire brush, or possibly electrolysis may reveal some part numbers.
