Thanks for the input, but......
things are going a little bit over and under.........

There are two main series of .22 by mauser, the first series with an small bolt as patented by Feederle- thats the series i am looking for, and in this series only for the model Mm410, as shown in my pic.

The second series appears in the middle of the 1930 and was called the "B" series, the bolt is completely different. ( these series is shown in the posted stoger catalog site).
