yes, the "Couger" (sic) has been around for some time, back in the days when all these barrels and parts were readily available, AND cheap, our shop did some in 4 inch ,6 inch and cut down 8 inch barrel to make two 3 inchers, BUT we never nickled them, this is all "class" all of ours were 'blued" and a couple were Metalifed SS (looked like stainless) did them on S&W's too..........this one belonged to and was done for one of the former cops who used to shoot with Bill Davis back in the day..........curious as to what it would be worth as we too had heard about the one from the Mansfield shows, some years back...imagine what a nickel 6 inch Python barrel would cost !!! let alone the cost of a "proper nickel plating" job.........
