Heads up Charlie Boorman new series Spitfire

An Early heads up for the new “Charlie Boorman Sydney to Tokyo by any means” features a Spitfire with a sharks tooth mouth. could this be the Temora Aviation Museum’s mk viii http://www.aviationmuseum.com.au/aircraft/Spitfire.cfm although the one shown briefly in the BBC2 advert has slightly different markings to the one shown at Temora? (Invasion stripes and what looks like the numbers 195410 on the rear close to the tail. Anyone know more please?)
