Disassembly and diagram for 1858:
http://www.scorrs.org/From the SCORRS website, browning a 58:
goal was to make the gun appear as if it might be an original cartridge conversion from the Civil War era. In order to do this, I chose to use a rust brown finish that is similar to what the original finish might deteriorate to over the years. I decided to try Barrel Brown and Degreaser, by Laurel Mountain Forge. It can be obtained from Brownells. I selected the Laurel Mountain browning solution, because it would not be necessary to be as careful about oil contamination on the metal parts.
I began by removing the bluing from the Kirst Konverter. I did this by using a product called Navel Jelly. Navel Jelly is normally used to remove rust from tools and parts. The bluing on a gun is essentially a form of controlled rust so the Navel Jelly does an excellent job of removing the finish.
Figure 7. The Remington is nearly finished. Unfortunately, this photo does not illustrate the deep red of the new finish, but it does show the loading port, the extractor housing, and the unique ammunition..
I started the rust browning process by sanding the metal with sandpaper.
