Pilot's seats post-Mod.2350
The pupil is seated in an ejection seat Mk 3 CT1 and the instructor in a Mk3 CT2.
The pictures in the back still show the original bucket seats.
The right hand seat, in either version, was excruciatingly uncomfortable after the first hour or so.
Would post a picture but quite beyond a technomoron.
