It's only half of the GL MkIII set. It's the APF (Altitude position Fix) trailer. There was also a ZPI (Zone Position Indicator) to complete the set.

Thanks Local Chap this forum is amazing at bringing the impossible to reality.I have never seen the Shilo photo,s before .I have gone from thinking I had the only REL radar trailer, to now they are like mushrooms popping up every where it is wonderfull to see. I suppose if we had the whole outfit we would have a couple of FWD HAR 01s and a C60L.
Has anyone found an ARN on any of the Australian trailers?
Cheers Ken

No Ken - are there any data plate positions on these trailers you may know about? Serial numbers? etc?

Perhaps a standard position that they painted the ARN & we may be able to rub or wet the paint to see what lies beneath.....

Tony the only data plate I have found is a tiny one on the turntable which is the Research Enterprise Limited data plate and that doesn't have much info on it. I haven't found anywhere that a plate might have been on the trailer and no sign of a ARN,I have a feeling I read some where that the trailers were made by one of the Canadian mainstream trailer makers.I haven't found any numbers stamped straight on the frame but I will have another look when the ground dries out and I can get up the paddock.
Cheers Ken

Robert that would be very nice to have and it is within border raid distance to.The data plate is very well preserved.Does your truck have a Canadian cab or an Australian one?
Cheers Ken

Just how I missed this thread when it was active in May 2011, beats me...the GL III(c) story is a major interest of mine and Local Chap's post is a good place for me to add my two cents worth. The on-line source for the three attached thumbnails was yours truly..in fact the two coloured images APF ( Accurate Position Finder ) and the ZPI ( Zone Position Indicator ) were taken in Shilo, Manitoba when it was first discovered ( 2006 ) that one GL III (c) had survived in Canada. The Canadian developed GL III (c) was the first centimetric mobile gunlaying radar to be put into mass production by the Allies during WW II. It represents a remarkable achievement by Canadian Scientists and Engineers when microwave technology was in its infancy. What is remarkable about the APF unit at Shilo is that much of the original (1942 )interior pre solid state electronics is still in place ( see attached ) and could be partially restored if certain obstacles could be overcome. I was aware of the two gutted ZPI trailers discovered in Oz by Tony Smith, but those referred to in this thread are new to me. Please get in touch by PM if you wish to dialogue further on this topic.
