This guitar was accompanied by a silver-plated metal plaque engraved '1958 Supro Dual Tone / Mark, Your past... our present / Love, Weston & Denny', designed to affix to the headstock.

Having mentioned that the Supro Dual Tone was just like a guitar he had growing up, Mark Knopfler received this guitar as a gift from mastering engineer Denny Purcell of Georgetown Masters in Nashville, during the mastering of his soundtrack album Metroland in July 1998. In the accompanying note, Purcell wrote: ‘Mark, it is such a pleasure for us to be able to give you a guitar just like one you once owned! What a wonderful connection to your past, our present.’

This guitar was auctioned at Christie's in London on 31st January 2024. It was sold for 40.320 Pounds.
