Fitted with a Turner Diesel engine. More details to follow.
In January 2012, Channel 4 television broadcast a documentary 'The Great Train Robbery's Missing Mastermind?', which investigated the possibility that one of the UK's biggest robberies may have had inside information. It's been reported to me that "One clip showed SXF590 (a soft-top LR) arriving at Leatherslade Farm as part of the police investigation in 1963. It had a lot of script on the side panel, but impossible to read what it was."
Any more information would be gratefully received.
