Riley,

I apologize if my post seemed presumptive. I made my assessment based on the fact that the hammer and trigger appear to be other than case hardened and the "plumb" color of the cylinder. Both of these things are giveaways that a Smith & Wesson is not in its original finish.

Just to clarify, there are relatively few of the 3rd Model H.E. guns that we call the "Wolf & Klar" Model with a 6.5" barrel (only estimated 100-150). Your gun appears to be a 2nd Model H.E. and the 6.5" barrel is most common in that model. If you are asking about the specific guns that have been "engraved" by W&K with a 6.5" bbl., I don't know of any estimates on those.
