The web site also lists Palmetto as the manufacturer. Note that the only review was posted in 2004.
Palmetto is apparently no longer manufacturing guns, having ceased in 2007. There may be a retail outlet at their former site in Brescia, Italy, and some sutlers may still be holding old stock.
Frankly, I doubt that the gun is available from Dixie. You'd probably get a Uberti if you ordered it.
