AZ S&W Guy you bought a beautiful revolver in wonderful condition for your collection that you really wanted and to me that's what it's all about. I have over paid for some in my collection and on others I got some at well below market value. The guns we buy are for us only and we pay what we think is fair to us for the gun based on availably and condition.
I think it's also like some other people have said and that is that you bought something built in an era when workmanship meant something and at a quality level not realized anymore. The guns made back then were hand built by real craftsman who took pride in their work.

Congratulations on the purchase.
