The new guns aspect is valid, however, there is a role for old, worn firearms also. I discussed this with a director for a movie that I worked on last fall. The time period was 1880 in a small, remote mountain mining town. I convinced the director that it would be entirely appropriate to have some C&B revolvers used by miners and a variety of cartridge conversion revolvers along with a few "modern" SAA's, Schofields, and 1875 Remingtons. The reasoning was that miners weren't flush with money and a cartridge conversion would run about $7. whereas a new SAA would be in the vicinity of $25. The C&B's and the cartridge conversions were aged and the SAA's and others not necessarily so.
