GORDON 50:
I’m sure I saw some Dairy Crest ones around in the late 90’s.
1890s, not 1990s 
Used one for flower imports,in the 90`s.Handy because you could (just about) open the sides and let the various importers rip away at their pallets,as the forklifts arrived.
Seriously heavy curtains,and,a chequerplate floor,as the moisture from chilling would rot a standard plywood floor.Aluminium side planks as well.
Not one of ours but image found on google

You can almost see the bulk of the insulation in the curtains.

Just like my old F16…what a truck! Volvos best… 
This is the only photo I can find of it. We used to load groupage here for Spain, I took this pic to show how close we were to the runways at Heathrow
B&Q still have a few of them, used for mixed deliveries of plants and stock.
Plants from Crew had some of the first of these, early 80’s
