Thanks for all the replies, you guys. I went and bought this thing, and though I haven't shot it yet, I can see real potential here. I'm kind of kicking myself for not trying the single shot pistol thing a lot sooner, because this gun shows incredible promise! It has wooden stocks, with no rubber, and the pistol grip and forend are a nice walnut. The blue is very nice with no wear, and it's a deep rich blue. The lever is the nicest plum color I've seen in a long time. The sights are sharp and easy to see. This gun just seems to drip quality. I have to agree with those who warned about not being able to stop with 2 barrels. I might be on a barrel hunt for other calibers now. I think I'm going to try and find the rifle stock set and a rifle length rimfire barrel now, and then try some of the other calibers like 35 Remington and 45-70 that I've been reading about for years. I'll start my barrel hoard by buying the other barrel sometime in the next couple of weeks and shoot 45 Colt and 410 shotshells from it. It should be a lot of fun. The serial number is in the 200xxx range. Any ideas as to when it was made?
