Well, I thought there was a reason I had to search so hard to find an I-frame Terrier for my own, and now I know what it is. All you other guys are scarfing them up! Antique41, you've made an entrance that is guaranteed to impress and let me add, "welcome aboard" for it.
I personally got on my I-frame acquisition kick about 4 years ago when it seemed like most of the guys on this forum couldn't even spell I-frame and couldn't have cared less. With the "help" and encouragement of my two favorite enablers, Hondo44 and DCWilson who egged me on from afar, I was able to grab up several as the interest here was just getting off the ground. Now everyone seems to be wanting one, and the one you got seems to be about the toughest to find. To complete my "trifecta" of snubs I had to pay more for the Terrier and had to "settle" for a pre-War example, even though I was searching for the very one you got. Congratulations, but be aware, you are on the top of a slippery slope... one will probably not be enough. You'll want at least a 32 HE, maybe a couple of Regulation Police models, and then of course a 22 Heavy Frame Target or two and..... it never ends! Welcome to the insanity. Here are a couple of my favorite pictures of some of my I-frames, the trifecta of a Terrier, a 32 HE snub and a Baby Chief (which is technically the first J-frame, but is really more of a coil spring I-frame size) and "Mutt and Jeff" the same 32 snub with its longer nosed target brother a 32 Regulation Police Target.
BTW, you might look for one of the rather commonly found pre-War Regulation Police models in 38 S&W with a 4" barrel to serve as company for your Terrier. No, I'm not an enabler, not very much anyway!
