Wow - blast from the past! The "Smolts" and "Cougars" were fairly unusual, and pricey back in the days of the wheelgun. As I recall, the major advantage of these revolvers was the looks and greater accuracy of the Colt Python barrel, along with the stronger lock work of the S&W and Ruger. I believe just about all of these were made for competition use - so I'd really inspect it well if you are interested in buying it. If it were me and the piece checked out okay, I'd have already bought it.

Good luck,

Dave
