I think this is GREAT!!! I would kill to have a restricted tartan with the paperwork to prove it. If I were you I would have it cleaned boxed etc... and keep it for bragging rights or list it for about a year and see what happens. You might make a pretty penny off of it. If you cannot "unload it" for a profit then donate it for tax credits at the end of the year. But I amd sorry I would not ask if Her Majesty would like it back because then it will be a yes and no maney will change hands.... If you like you can always let me know your asking price, I just might send you the cash.
