I believe there are 4 two seaters based in the UK. ML407 based at Duxford, IAC 161 based at Duxford (currently in dutch markings), MJ627 based at East Kirby. These three I think are Supermarine conversions and also PT462 based in Wales and occasionally at Duxford which was converrted by Charles Church.
There is rumour on another forum that the MkVIII Trainer could be returning home.
