Welcome to the forum! If you intend to stick around a while, please go to the introductions section and say hello.
I can't give you much info on that gun other than tell you I have a soft spot in my heart for H&R revolvers, my mom has a 922 that was the first handgun I ever shot.
These were designed to be good quality, yet affordable guns. If you want to get an idea of the value, you can check Gunbroker.com or a gun traders guide or gun digest.
Oh, please post pics of it if you can, we love gun porn around here and it will help us to give you an estimate on it.
