This merely proves the point that we never really own our guns, we are just merely caretakers while we still draw breath. There are lots of guns out there like this that have fallen through the cracks of time and are waiting to be found.
This also answers the questions about having a plain Jane revolver lettered. They aren't all engraved on the side with the names of the famous former caretakers.
You have to beat the bushes and do the research.
Charles, congratulations on a great find and thanks for sharing the story. This is what takes gun collecting to a whole new level.
