Congrats Frizzellr! Sounds like a good buy!
If you are really interested in finding the age of your gun go to Rugers web site. Using the serial number they will tell you when the gun was made.
I made a really good deal on a Ruger Super Redhawk a couple of years ago and through the Ruger' s site I found out that it was only a few months old!
Someone bought the .44 and I guess found out that it was too much for them!
Again congrats on a good purchase!
