I had this posted on another forum and it was suggested in that forum for me to post it here in this forum in the hopes of gaining more knowledge from all of you. I am certainly no expert by any means, but I sure think this is an interesting find. Here is a copy of my post... Please do bear with me as I am new in both this forum and in collecting these. I was recently at an auction and fell in love with this set. I won the auction and after days of researching what I could find both in your forum and online I think I have a basic understanding of what I now own. Subsequently, I think I have also caught the bug and want to grow my collection. But for now I would like to pick your brains and see what you can tell me. I am not having much of any luck finding information about these numbered boxed sets online. I put the photos in a public album on Flickr and will post that link below. - 7 1/2" octagon barrel. - Looks like a replica of the Colt 1851. - The date code XVI shows this is 1960. - Proof marks on the right side (provisional Gardone proof consisting of a star surrounded by eight lands and grooves over a coat of arms featuring a hammer and anvil and crossed bayoneted rifles, and the star surrounded by eight lands and grooves over the capital letters PN which is the first black powder proof for Gardone and Brescia) along with Made In Italy and the G.U. initials (Gregorelli & Uberti). - Navy Arms Co on top of the barrel. - Left side marked Navy Arms Co. - Bottom of the barrel is marked with the same two proof marks as the right side. - Underside is marked with 3545, which is also the same numbers marked on the paper, the box, and the tool. The tool is also marked with the numbers 55 just like the cylinder. - Cylinder has the same proof marks, and the numbers 55 are on the side that faces the hammer. - Powder flask is marked Navy Arms Co. and Made In Italy, and has "Colts Patent" on the front in the image. - The caps container is unopened. - Can't find a serial number. Unless it is the 3545? - Gun appears unfired. Here is the album. Hope you can see the photos this way. https://www.flickr.com/photos/[email protected]/albums/72157692664573182 I also included a photo of the other flask that came with the auction win, and put it next to the flask from the case to show a size comparison. Thanks in advance for any knowledge you can share.
