TDM, Trago Mills exists as a couple of (allegedly) budget superstores in Liskeard Cornwall and Newton Abbott, Devon. The most noteworthy thing about the stores is the overt politicisms that litter the place - one would get the impression that the owners are a little bitter about the UK ever having entered the EU - go along and judge for your self! It really is rather funny!
They did try their hand at a little aircraft manufacture though a while ago and if I recall attempted something Slingsby-esque in Cornwall. I don't know if failing to get a military trainer contract had anything to do with their demise, (maybe I have had one pasty too many today) but I recall sombody relating a tall tale to me along these lines.
The "Trago Mills" was an aircraft and they still had a hangar at Bodmin Airfield a couple of years ago.
