This golden bullet is a licensed replica built by S.D.Studios for their successful James Bond prop replica run a few years ago. I beleive this bullet was originally intended to accompany the full Golden Gun replica that the company also made.
As far as quality goes, this piece is almost top notch. Very well crafted and finely shaped, the only complaint I have is that the numbers "007" appear silk screened onto the bullet, whereas in the film, they seemed to be machined into them, or perhaps cast into the bullet itself. I'm no munitions expert, so what the hell do I know. Either way, it's a find addition to my collection, and I'm very proud to have gotten it directly from Steve Dymszo.
Though not a particularly spectacular prop in it's design, I am happy to have it in my collection as the golden bullets played such a pivotal role in the story arc of the movie.
