My understanding is, the reproductions that have been made are so far below the originals in quality that they're not worth owning. Nothing like Mil-Spec quality. I once had one and it was a piece of junk.
When I handled a couple of real ones, I was very surprised at just what a nice rifle they were...
Get a good original with a shot out barrel and have it rebarreled to 19" seems the best route...although touching a historic piece could be sacrilege and all. Or better yet buy one that's already been done...
