john1950 Posted June 22, 2020 Share Posted June 22, 2020 I am just putting some points of interest forward, I think the composition of the original photo is pretty well decided or agreed to differ. Wally your recall and access to numbers is remarkable. Quote Link to comment Share on other sites More sharing options...
wally dugan Posted June 22, 2020 Share Posted June 22, 2020 JOHN l think this will rumble on the primer movers mentioned as candidates all have one thing in common they are all of a similar length give or take a few inches l am lucky that l have a ministry of supply copy SCHUDULE OF ALLOCATION OF REGISTRATION NUMBERS T0 VEHICLES POST 1948 as well as the index file list of key cards covering 1945 to 1950 which covers rebuild vehicles REGARDS WALLY 1 Quote Link to comment Share on other sites More sharing options...
cosrec Posted June 24, 2020 Share Posted June 24, 2020 Bit more fuel on the fire I am willing to accept this is a Diamond T and the illusion at the front end is caused by shadow camera angle etc. Indeed i think it is the only answer. So you guys out there have identified the tank i believe. So could this have been a private civilian company picking up a tank to take it to the North east were many where cut up. i know many of the civilian used cobbled up trailers made from ex mod parts Quote Link to comment Share on other sites More sharing options...
john1950 Posted June 25, 2020 Share Posted June 25, 2020 (edited) Unfortunatly any answers will be just pure speculation unless someone comes up with a more detailed image. If as seems likely the trailer is a prototype or early production 50 ton it would not have been released for civilion use. I am going to hang my hat on a still service transporter, coming from the Barlow storage area. Edited June 25, 2020 by john1950 1 Quote Link to comment Share on other sites More sharing options...
the DT guy Posted July 15, 2020 Share Posted July 15, 2020 evening every one i have been reading the book about Cranes of Dereham "we built trailers" and there is a very small paragraph about them being asked by the mod to design a trailer with 50 tons capacity in the late 40's. Cranes produced drawings and built a prototype which reading the description is the same as a Dyson 50 ton. ounce the prototype was built and tested the mod gave the drawings to Dyson who then got the contract to build the trailers. so is the photo of the prototype built by Cranes? or one of the very first Dyson built trailers?

wally dugan Posted July 15, 2020 Share Posted July 15, 2020 As the Dyson was built to the same specification as the Crane it would be hard to tell from the present photograph a shot of the trailer would have been great as l have the list of the first fifty registration numbers allocated also the plans and drawings for the Dyson Quote Link to comment Share on other sites More sharing options...
the DT guy Posted July 16, 2020 Share Posted July 16, 2020 a clearer close up pic of the trailer would certainly help the identity as Cranes used a lot of the same parts as used on their 40 ton trailer. the large castings that carry the axle springs are very distinctive to Crane trailers. i am basing my assumption that this might be the Cranes trailer on the date the photo was taken as it's mean't to be prior to the Dyson built 50 tonners. out of interest Wally how detailed are the plans and drawings of the Dyson that you have? regards sam Quote Link to comment Share on other sites More sharing options...
john1950 Posted July 19, 2020 Share Posted July 19, 2020 Having had a look at the photo on Britain From Above. I think It is a Diamond T but with a 3 line axle configuration and the blured image behind the lead axle is the brake wheel. Just another hypothosyse.

wally dugan Posted July 19, 2020 Share Posted July 19, 2020 JOHN you are going to hate me for this the brake wheel is on the nearside in the middle of the trailer and cannot be seen from the off side as its behind the stowage box on that side Quote Link to comment Share on other sites More sharing options...
john1950 Posted July 19, 2020 Share Posted July 19, 2020 (edited) Some trailers have a wheel painted white behind the offside front tyres, there are several photos on the web clearly showing its position. This is an ongoing friendly/fun discussion/debate. Edited July 19, 2020 by john1950 Quote Link to comment Share on other sites More sharing options...
wally dugan Posted July 19, 2020 Share Posted July 19, 2020 SAM l have a number of drawings on the 50 ton some are small but give only details the larger ones are four foot by 3 foot and are design drawings that came from DYSON to FVRDE and where sent in april in to storage as they are to large for me to do any thing with but may come back in the future Quote Link to comment Share on other sites More sharing options...

john1950 Posted July 19, 2020 Share Posted July 19, 2020 Rogers has h/brake wheel at the N/side in front of the rear bogie. Dyson/Crane trailers have the h/brake wheel behind the o/side front wheel. Seems to be a design difference. 50 ton diagram is interesting Quote Link to comment Share on other sites More sharing options...
wally dugan Posted July 19, 2020 Share Posted July 19, 2020 JOHN the focus has generally been on the DYSON 50 TON and l have to admit that l have not done much on the crane- dyson and rodgers 40 TON but l will scale the drawings l still have at home to see if there is a feature that appears on one and not another Quote Link to comment Share on other sites More sharing options...
john1950 Posted July 19, 2020 Share Posted July 19, 2020 (edited) Hi Wally It is just the image of the item bebind the first axle is so blured and indistinct it could be a wheel and tyre or something else. I await your further comments. Or it could just be my eysight. Edited July 19, 2020 by john1950 Quote Link to comment Share on other sites More sharing options...
wally dugan Posted July 19, 2020 Share Posted July 19, 2020 (edited) JOHN l found my ministry of supply data book it lists the difference's between the rodgers and the two marks of the crane-dyson 4OTON trailers. Some are not visible in the photograph but the british made trailers have the brake wheel on the nearside the rodgers on the offside also the deck on the three 40 ton trailers is level but on the dyson it has a slope. this beats looking at colour charts and decor with the wife Edited July 19, 2020 by wally dugan Quote Link to comment Share on other sites More sharing options...
john1950 Posted July 19, 2020 Share Posted July 19, 2020 Wally, I had the brake wheel and the makers of trailer the wrong way around. I think the 50 ton needs a slopping bed so that the second axle has clearance/room to move vertically, as well as ease of loading. A bit more usefull information about trailers, from the records. What would you say the latest most up to date guess is. Quote Link to comment Share on other sites More sharing options...
wally dugan Posted July 19, 2020 Share Posted July 19, 2020 JOHN looking at the design of the three RODGERS and CRANE-DYSON 40 ton and the DYSON 50 ton and a unhelpful photograph l think it looks more like DT and DYSON 50 TON the trailer in the photograph looks to have a slope but that could be down to the angle it was taken at and the brake wheel is tucked under the body and close to the tyre would it cast a shadow if it was a RODGERS its still a puzzle without a better picture from a different angle 🙄 Quote Link to comment Share on other sites More sharing options...
the DT guy Posted July 19, 2020 Share Posted July 19, 2020 pics should help with the differences between the trailers John & Wally. but Diamond T with a 50 ton looks bout write to me. regards sam Quote Link to comment Share on other sites More sharing options...

wally dugan Posted July 20, 2020 Share Posted July 20, 2020 (edited) JOHN l have looked and enlarged the picture between the front and back axles there appears to be a oblong shape the stowage box? or just a trick of the light got to admit it does more look like the 50 TON so until some one comes up with a new prospective on the photograph that's were my money is WALLY Edited July 20, 2020 by wally dugan Quote Link to comment Share on other sites More sharing options...

john1950 Posted July 21, 2020 Share Posted July 21, 2020 If the 1.35 Merit model is correct the parking brake wheel has a position on the near side front, left front corner of the trailer bed as well, mounted verticaly. Quote Link to comment Share on other sites More sharing options...
