It's just a buckle. However, it is the rarest buckle I have ever seen. It is of course the sword-belt buckle of Jack Aubrey (Russell Crowe) from the motion picture, MASTER and COMMANDER.
Several years ago I saw one very similar to it on Ebay. I was alas outbid. Since then I have tirelessly searched for one to no avail. I am posting it so that if anyone runs across one, please be sure and let the Beachcomber know. Cheers.
