Mine is 42208X...a 4" taper barrel in what I would describe as excellent, used condition. Got it off armslist a couple years ago when I noticed the seller could only be a mile or two away. No model number.
Put in a bid, he took it we met and did the deal, and I was home with my pre Model 10...all in about an hour.
I do shoot it from time to time, and it is currently loaded with 135gn +P. However, I prefer my Model 15. I may move it along one of these days. I have a hankering for a 3" Model 36.
