This is an interesting old pistol. I believe it started its life as a Remington new police black powder. At some point in time someone made a cylinder for 22 long rifle and took a Remington rifle barrel, Milled it crowned it and threaded it to the frame. It shoots really well for its age. This pistol is well over 100 years old. I have no way of pricing it as there is not one like it. So I guess 400ish? Interested in trades as well. I can add cash Call or text 239-601-7756
