Naugler. I had a .36 Paterson replica. Nicely made, no loading lever. Navy arms manufacture if I remember correctly. It was a pain in the kazoo to load it but once it was capped and ready to go it was almost as accurate as some of my other percussion revolvers. The trigger took some getting used to. I can see whay it was such a popular gun for it's time for folks who could afford them, especially if they carried a spare cylinder or two. Compared to the common single shots it was a technological breakthrough. On the other hand you can see why later percussion Colts were an improvement, especially the addition of a loading lever. The revolver I had was nicely finished, had good lock timing. I ended up with a broken trigger spring after some use but this was easily obtained at the time and I had no further trouble with it. I probably put close to 800 rounds through it over a three year period and had a lot of fun with it. In retrospect if I was going to buy another one I think I would opt for the model that has the loading lever. Hope this is of some use to you. best regards, Joe
