White Rickenbaker

Hi, really a question for Bill,after many years and now arthritic hands and financial reasons,it has come to the time to sell my ex Bill's white 12 string Rickenbaker ,signed on the back by Bill with a message to look after his guitar and stay young.I just wanted to know if Bill would mind me selling it, I know I have compensated for its loss in part by the red strat, but I just still feel bad about the way it left his possesion.John
