Lou, the prices for USFA single actions in general and particularly for the higher end, less encountered models have gone bat guano crazy. I have a Pre War USFA with all US sourced parts and the less encountered black powder frame. I paid hundreds of dollars less than half of what that seller is asking. At the time (2-3 years ago) I thought I was a bit crazy for spending $2K on a revolver but in retrospect it was a good deal.
I would like to have a USFA 44 WCF but they are as rare as hen's teeth with gold fillings. Unless I stumble across a miracle deal I'm never going to buy a USFA single action again. Just too much money these days.
