RE: Has anyone heard of Western field guns?
One of the nice things about being an NRA member is that they will provide you information on just about any gun you can dredge up. Send them a good description of the gun, markings, and/or a photo and they can tell you all about it. They've been around since 1873...If they can't ID the gun for you, no one can. Only thing they won't do is put a value on it.
If any of y'all aren't in the NRA, you need to get there. I can sign ya up.
