JayCee,

Nice catch. I didn't know about that page on the site. So "Fabbrizioli Mario" was registered as a gunsmith with a trademark at the "Test bench of Gardone Val Trompia (Brescia) from 1945 to 1980".

Interesting, I don't see any other proof marks on the gun. I would not have thought that was possible, but there is always something to learn...
