Sorry Danny and Jackbut I cant agree with you. One assumes that they are now in the possession if his family, who are entitled to do with them as they wish. If they are purchased by a wealthy collector (and they are going to have to be wealthy) then I see no problem. The FAA Museum has no particular claim on them, moral or otherwise. If they want to make a display about Captain Brown's flying career (and I'm sure they will) they could include a replica of his medal group which could be obtained for a few hundred pounds. As Jimlad says, it's not the medals themselves which are important (they are just chunks of metal after all) but the story behind them, and that is available to all, no matter who owns the actual medals.
