Unusual Royal Mail trailer

[ChrisH-UK]

While browsing photos of Carlisle I came upon this pic https://www.flickr.com/photos/d9006/8500552426/

 

In the background is a Royal Mail truck, obviously an artic, and remembering how small that vehicle area was at Carlisle station, obviously a small one. I did some research and figured out it was a Seddon Atkinson 3-11 daycab. What I can't figure out is the trailer, roller shutter door on off-side, and presumably single axle. I've checked a couple of commercials sites and found lots of tandem axle standard trailers and one or two single axle plain trailers but nothing that matches that. Help!

I have a copy of the ‘Mailvan Handbook’ which is actually quite interesting!

 

Unfortunately this is all I can find out regarding the Seddons. There isn’t a big section on different styles of trailer. It may have been a one off, as many times vehicles were customised for the locations they were used in. 

 

Hope its of some use
