Good morning John, sorry I'm late to your post been busy making visors. You might have seen my BRe it's the gaff rigged cutter ketch. I had my sails designed and built be a friend who works for Moat sails, so I have also been down the road of Jib and "Flying Jib". Only I have mine from new and on my own bowsprit, so not quite the same. However my jib/staysail combination on a reach is very powerful. The original thought was for progressive reduction of sail area as I mostly single hand as a consequence having a highly efficient furling system was essential. So I bit the bullet and bought Harken and doubled the Halyard and fitted Dyneema. The result I can point very close to the wind at 5 knots and in a blow like other Raiders drop the main and continue. My high cut jib, remarkably similar to Graham's is 3.55sq.m. with the sheets leading back to the same cutout the mizzen sheets are fed to. If Matt cannot help you I'm sure Moat sails can build you one in White. My Bowsprit, just like yours is supported by a "Bob Stay" or "Dolphin Catcher" led to the same winch point.
