This may be a newbie question, but what is the difference (if there is one) between an SW 66 and an SW 66-2 or other number, is it just a matter of production run or...? Because I've noticed price differences based on the number after the 66...just wondering what it translates into practically...

The so-called Dash numbers on S&W's refer to factory modifications made over the production life of the gun.
The first revolver in a Model has just the model number, like Model 66.
After a few years, slight changes are made to some part or parts, and the model is changed to a Dash-1, or revision #1.
The Model 66 was introduced in 1971.
In 1977 the gas ring was moved from the crane to the cylinder, and this was the Dash-1.
In 1982 the cylinder counter-bore was eliminated, and this was the Dash-2.
I think the Model 66 is now up to Dash-6 or so.
The Dash models are of primary interest to collectors. There is really little if any practical difference in versions, up until you get to the major changes like the move to a firing pin mounted in the frame, and the use of MIM parts.
