Beautiful gun and thanks for sharing your story...

Interesting features on your gun that you may want to get a S&W letter...

The grips are mid-60s vintage but generally didn't come stock on the gun...and either did the Target Hammer and Target Trigger. They could however be special ordered and I've seen a couple with the original boxes that indicated they came from the factory that way... By any chance is the serial number stamped inside one of the grip panels? Generally only the Magna style grips have numbers in them,,,

Welcome to the forum...a great first post...
