That was fast! I just came back to edit the post. It doesn't have a hammer. At first I thought someone disabled it, but that doesn't make sense. Was there a hammerless/concealed hammer model then?
I don't have access to a camera right now, except on my phone.
The barrel is about 2-1/2" long. I don't know how to judge condition or whether it is 5 or 6 shot, but I'm guessing 5.
