Tony B Posted September 27, 2013 Share Posted September 27, 2013 Alert looking security! :-D Next question what does the X prefix mean? Quote Link to comment Share on other sites More sharing options...
Maurice Posted September 27, 2013 Author Share Posted September 27, 2013 all trailers had an x as starting code , like an A on Ambulances and a T on armoured. Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted September 27, 2013 Share Posted September 27, 2013 So, RDF equipment, self-contained, in the trailer, with crew. We know it needs two units to track a source, so why not have a similar RDF unit in the towing vehicle? It tows the trailer to one location, drives to another location, and when the job is finished picks up the trailer and hauls it home. Any evidence of the same RDF gear in a medium sized vehicle suitable to tow this trailer? Quote Link to comment Share on other sites More sharing options...

Thinking about drawbar heights and this being a specialised outfit, there is a possibility that the QLR assigned to this role had a special lowered towing hook to make the trailer tow level.

David B. Posted September 27, 2013 Share Posted September 27, 2013 According to the Ministry of Supply publication, Data Book of Wheeled Vehicles, the draught eye on this trailer has an ID of 2 21/32" so that it can be towed by a 3 tonner. I have my doubts about it being towed by a 4x4 though as a QL has a tow hook height of 2' 9 1/2", where as an OY is 2' 3 1/2". The height of the trailer eye is 2' 1 3/4". All this from the data book, it also states that if the lorry were laden the tow hook height would be 3" less than given, this would still make the trailer tow too high at the front if behind a 4x4 (QL). Regards Richard ,I think you are quite right. I noticed this thread while I was away without the Data Book to hand. I did a similar comparison with the 10cwt tow eye height versus truck tow bar heights once and it seemed that to me that the largest British truck which could comfortably tow a GS/Mortar trailer was the OY. The 4x4 three tonners tow hook was too high as you say. Regards Maurice - hope you are well. What a lovely trailer, are you sure you can't lie down in the back of it ? All the best, David.

Any evidence of the same RDF gear in a medium sized vehicle suitable to tow this trailer? One: the units have to be around two miles apart to triangulate decently. Two: They operated very close to the front line, sometimes over so needed to be able to Foxtrot Oscar at high speed. What happens in case of breackdown, two units U/S. Yes DF sets were fitted to units such as the Heavy Humber and the WC54 (Got to get the Dodges in somewhere :-D)Posibly WC62 as well, at least they were used by support parties attached to US units. Photo of trailers was taken in Germany 1945. Quote Link to comment Share on other sites More sharing options...
nz2 Posted September 27, 2013 Share Posted September 27, 2013 Looking at the photographs of your trailer shows a design similar to what I have planned for use as accommodation at rallies, as it fits a period of time that could be dated even earlier than WW11. To make one of similar proportions can you please measure the dimensions of this trailer. I take the wheels are 16 inch from a Morris or similar. How wide are the timber boards for the walls and how thick are they. Thanks Doug Quote Link to comment Share on other sites More sharing options...

Maurice Posted September 27, 2013 Author Share Posted September 27, 2013 David , yes you can lay down in it , but your legs are sticking up the wall:-D, I got some drawings from the interior , very cramped , if you slide through the door onto your seat at each end , than that is about it . got frame back from shotblasting today , needs a few holes in the drawbar welded up , didn`t see them before the shot blasting . will mesure it up , but the dimensions are given in Canada`s fighting vehicles europe 1943 45 . frame is same as mortar trailer and GS .

Tony B Posted September 28, 2013 Share Posted September 28, 2013 I would not want to Foxtrot Oscar too fast with that trailer :-D A 88mm as a starting gun? The vehicles at least operated on the move intercepting. A standard trick was to rig ropes with a weighted tin attached bettween the radio benches and have a Primus in it so tes could be made at any time. The German's wern't stupid, so any sites, high and clear of solid objects, were either mined before withdrawl or bracakted by artillery. Not an easy option job.

Gordon_M Posted September 28, 2013 Share Posted September 28, 2013 http://goldbeach.org.uk/Y%20service/Direction%20Finding.htm Very informative, thank you. So now he needs a Morris to tow it and two sets of ariels and mounts. I think the trailer would be rarer than the Morris. Quote Link to comment Share on other sites More sharing options...
Maurice Posted September 28, 2013 Author Share Posted September 28, 2013 no no , I know 2 Morris cs8 for sale in Belgium , a 6 cilinder and a 4 cilinder version , each tempting , but I have got enough 15cwt`s . I can pull it with my Chev C15A wire3 , or my Fordson WOT 2 Radio truck , and Bedford MW and Chev c15 11Cab to choose from . Quote Link to comment Share on other sites More sharing options...

Tony B Posted September 28, 2013 Share Posted September 28, 2013 (edited) Yes that is the correct installation. Where did you find it? I only know one copy of those documents. As for which 15 cwt. What Y Service wanted they got! They had the power to commonder anything they wanted, any questions will lead a stiff talking to withourt coffe at least.

Richard Farrant Posted September 28, 2013 Share Posted September 28, 2013 I only know one copy of those documents. Tony, The contract for these trailers was for 200, so there is bound to be more than one copy of any document regarding its installation.

Tony B Posted September 29, 2013 Share Posted September 29, 2013 Yes but they were classified at the time, and very few seem to have survied. I spent a long time looking for a set! Quote Link to comment Share on other sites More sharing options...
