I have an armi san marco brass frame remington 1858 new model army and was looking to buy a steel frame. I know where I can get a steel frame, but I don't know who makes it. All I know is that it was distributed by navy arms while they were in new jersey. I know that navy arms distributed uberti, pietta as well as armi san marco. So I was just wandering if my armi san marco parts will fit with either a uberti or a pietta frame. Thank you.
