I ended up with a Ruger New vaquero, 3.x inch barrel, birdshead.
Not going to try to talk a fellow out of something he wants. But just as a reality check I got mine earlier this year for just under $600 with shipping and FFL. Modern Ruger, I get six in the cylinder with a transfer bar.
Just saying, I think Ruger made these for Lipseys or somebody like that around 2002 or so and they are starting to dry up, 4 versions available pick either .45ACP or 45Colt, pick either black or stainless.
