Cimarron Firearms in the US has Uberti make them an 1851 Man With No Name revolver just like in The Good, the Bad the Ugly. Calibre is .38 special. You can spend big bucks for the one with Blondie's snake, or stick with the plain Tuco gun. They look exactly like the original 1851. The "ejector rod" is actually part of the loading lever assembly. Wolverine gets them once in awhile. Talk to Grumpy. You can also see them on Irunguns site.
