The duxford VC-10 is the last surviving type 1151 super (that has not been converted to an 1180) it also holds the subsonic transatlantic record, the only airliners to have crossed the Atlantic faster are concordes. One other 1151 does exist, at bruntingthorpe, that is ZD241, ne้ G-ASGM however that has been converted to a type 1180, (K4 Tanker) leaving GC as the sole surviving 1151.
I believe at this time GM is to be preserved as a 'runner' for 'fast taxing'
