Not a clue from your initial description but here's some thoughts on how to further identify this item. But pics are great, so if you are able to scan or take pictures (even with a phone), they can be uploaded to a free site like imageshack.us then once hosted there, it can be put into a post.
'Perfect condition', would you say it's a mass reproduced item, maybe this could be a marketing promo item, or are you leaning towards it being one of a kind?
How did you get this item, is it authorized in some way? Many of the production people have been selling off their collections.
Another place to ask is The Star Wars Collector's Archive: http://theswca.com
(This might be all their Revenge of the Jedi items: http://theswca.com/index.php?action=disp_items_by&items_by=film&id=3)
Actually this sounds fairly close:
