Richard's Posthumous Effects

Having read somewhere that another of Richard's books has just turned have any of the learned folk on here come across anything in the sources to indicate what happened to the stuff that was looted from his tent (and indeed his body) at Bosworth?

I know they found the 'Bosworth Cross' but is it all out there somewhere, tucked in some French wardrobe? Can't imagine that stuff of such value (including armour) isn't still around. I know MB 'inherited' a lot of his books, but what about all the things outside London that went walkies?
