I believe that the honda factory bikes were indeed destroyed for the most part. I believe that some are in the very extensive honda museum and others slid into private owner hands, but many didn't.
the VF750 there looks like the one that (if memory serves me correctly), Howard Lees, Matt Oxley and Vesa Kuhltal??? (finnish guy - could never be bothered to read to the end of his name) rode to a class win in the Bol d'or in 1984. I think the team went on to be "Team MCN" and then "Phase one endurance"
here's some history that i ought to re-read
