This is just the right side....
The red dot at the right has a 17 stamped on it. I'm not sure if that is a serial or what. The big circle is just where the barrel catches, you couldn't see it in the picture.
I'm using a low quality web cam so thats the best I could do. There is a J stamped under the barrel between where the stock catches and the barrel hooks. It says it's a modle 22-410.
