Guiseppe,
Firstly welcome to the Forum. I too can see no issues with your rifle it looks a fair reflection of the breed with numbers everywhere.

Ask yourself the following questions:

1. "Is it firing right and doing what it says on the box so to speak?"

2. "Did I pay a fair price for what was sold to me as an authentic rifle?"

3. "Did you buy the rifle not the history alleged to have come with it?"

Hope this helps you
