Welcome to the forum. You need to make the acquaintance of Ron Curtis' web site:
Smith and Wesson Model 2 Army Revolver
There's some great stuff there. Model 2s are becoming more valuable as time goes by, and even beat-up and incomplete guns are commanding prices of a few hundred dollars. Complete guns in ordinary condition are several hundred, and good examples can go for well over a thousand.
Feel free to post pics of yours. There is a thread in the Forum Office section of this board that tells you hows to use Photobucket to host images. Or you can just attach to your post images from the hard drive of your computer. For that you use the "Manage Attachments" button further down the message post page.
