Hold on---might be wrong--- but pietta's ad offers the Josey Wales gun that he recovered from the (yankee Red Legs) on his farm after his family was killed and his farm was burned. Um, I too haven't seen this one in awhile, but my recollect was that gun
was his(Josey's gun) that he had kept hidden and it was either an 1861 n/or 1860 army that was a colt cartridge conversion with tube on right side of barrel w/extractor rod missing. And it was the same gun that the Indian woman snuck up on him and the other indian with. They did not have those during Civil War but maybe 4 or 5 years later! And, he carried 2 Walkers, an 1861 navy, an 1849 pocket and a Sharps throughout movie.
