http://www.davide-pedersoli.com/FuciliCategorie.aspx?lang=en you can go to Davide Pedersoli's web site and look at it. I think you can order one off there or they can tell you who carries them in the States.. that looks like a real hog leg. Interesting that it comes in .45 & .50caliber. Which one do you fancy?

Good luck.
