I think there's some confusion between G-HUEY and G-UHIH.
The former, the RAFBF's Argentinian Trophy, was last known based at North Weald, in flying condition and syndicate-owned from about 2004-2007, until allegedly grounded by a whole host of ADs. Now rumoured to be flying in a West African country.
G-UHIH is based near Blackpool, genuine ex-Vietnam, in tip-top condition, and on the air-show circuit.
