The Scouts in question are owned by a private individual and are kept in the original livery. They are based at Redhill in the Hangar used by Gatwick Avionics - a call to tony O Kill 01737-822215 mob - 0850 152033 (Gatwick Avionics) will enlighten you.
Incicidentally, Derek Jones -ex Bristow did a test flight in them for pilot magazine a couple of years ago, they may be worth contacting.
