I saw one of these in a gun store Monday while I was on a trip. They were asking $350 for one that might have been a bit under 90%. I didn't feel that was out of line since the last one I saw was in the same neighborhood.
Colt made two versions of this revolver. One was single action only. Target shooters cocked the gun for each shot anyway so double action wasn't needed. More double actions were made, so I think the single action models might fetch a bit higher price.
