I was wondering if anyone you might know the value of a Ruger Mark I. My dad has one that he purchased in, I believe, the 70's. I know that there was a recall on some (possibly all?) of them because when they where dropped they would have a tendency to discharge dispite their internal hammer. It hasn't been fixed according to the recall so I don't know if that would drop the value. Also, because of the Mark II and III, apparently more superior, I don't know if this gun has lost a lot of value because of that and would be considered obsolete or what. If you could help, I'd appreciate it.
