I bought my Colt.45 from Doc Rowland too and I can give to him an "A" plus. Great person to deal and talk to.
BTW, talking about Vaquero... I want so bad to find one but not the New Vaquero, but the old model Vaquero (3 screws). I don't care how bad is the shape of the gun, but it has to be an old model Vaquero.
Sorry, but you are mixing up your Ruger terminology.
3 screws and 2 screws are the difference between the original Blackhawk and the New Model Blackhawk design, circa 1973.
To quote that bastion of eraseable, questionable facts called Wikipedia:
"Two major variants of Vaqueros exist. The "Old Vaquero" was marketed from 1993 until 2005, and was slightly larger than the Colt Single Action Army. The New Vaquero, produced from 2005 to the present is closer to the dimensions of the Single Action Army"
The "Old Vaquero" was never called that; its simply a Vaquero, and that's what will be printed on the frame. It was on a New Model Blackhawk frame, and hence 2 screws. But yes, it helps describing it as "old Vaquero" to ensure you are talking apples to apples with someone.
New Vaquero is on a smaller and weaker frame, but is the current production gun. Still, it is a "2 screw" as well.
Check EE and some of the board dealers. Vaqueros can be had, just have to have patience. Bisley Vaqueros, however, are like hens teeth...
