As I said elsewhere I'v had a go at making TET a bit warmer now its getting colder out there, dug out an old tilt rear I cut off and saved to use as a fume curtain, couple of holes and jigerypokery and its in

Will find out if its any use tomorrow when I take some bits in the back of TET to get blasted.
And just to make sure I don't lose anything finally got round to "fixing" the rear buckle that had come unstitched 
And replaced the old broken plastic type rope on the bottom of the rear flap (fnarr) with something a biot more proper (actually old school washing line  )
