Dance Bros. pistols were first manufactured in Columbia (what is now known as East Columbia), Brazoria County, Texas, not Columbus, Colorado County, Texas. Later the factory was moved to Anderson, Grimes County, Texas. I have been to the sites of both of these plants and have seen Dance parts that were excavated from them. Dixie Gun Works of Union City, Tennessee is the only U.S. distributor for the Pietta reproduction Dance. The reproduction that they sell is incorrect as it has a squareback trigger guard whereas all Dances had oval guards. Also, the grips are just a little bit smaller than the original. Having said that, it is overall a pretty good reproduction. Of course, it does not have the unique Dance rifling, but they are made well. I have not fired any lead from mine, only used it in reenactments. I have mine at a gunsmith now having the trigger guard modified to the correct oval style and silver stars inlaid in the grips. A friend of mine, Gary Wiggins, wrote the only book that has been published on the Dance that I know of.
Also, regarding the .44 cal. "reproduction" M-1851 Navy pistols: these are not actual reproductions, but fantasy guns as no .44 cal M-1851 Navy pistols were ever made by Colt nor any of the various Confederate copies. They were all .36 cal. Also, Colt never made the M-1851 in brass frame. All brass frame versions of the .36 cal. M-1851 were of Confederate manufacture. Also, no M-1858 Remington pistols were made in brass frame. The closest to this model in brass was the .36 cal. brass frame Confederate Spiller & Burr.
